/*
The "put" command is for any process that wants to insert a job into the queue.
It comprises a command line followed by the job body:
put <pri> <delay> <ttr> <bytes>\r\n
<data>\r\n
It inserts a job into the client's currently used tube (see the "use" command
below).
- <pri> is an integer < 2**32. Jobs with smaller priority values will be
scheduled before jobs with larger priorities. The most urgent priority is 0;
the least urgent priority is 4,294,967,295.
- <delay> is an integer number of seconds to wait before putting the job in
the ready queue. The job will be in the "delayed" state during this time.
- <ttr> -- time to run -- is an integer number of seconds to allow a worker
to run this job. This time is counted from the moment a worker reserves
this job. If the worker does not delete, release, or bury the job within
<ttr> seconds, the job will time out and the server will release the job.
The minimum ttr is 1. If the client sends 0, the server will silently
increase the ttr to 1.
- <bytes> is an integer indicating the size of the job body, not including the
trailing "\r\n". This value must be less than max-job-size (default: 2**16).
- <data> is the job body -- a sequence of bytes of length <bytes> from the
previous line.
After sending the command line and body, the client waits for a reply, which
may be:
- "INSERTED <id>\r\n" to indicate success.
- <id> is the integer id of the new job
- "BURIED <id>\r\n" if the server ran out of memory trying to grow the
priority queue data structure.
- <id> is the integer id of the new job
- "EXPECTED_CRLF\r\n" The job body must be followed by a CR-LF pair, that is,
"\r\n". These two bytes are not counted in the job size given by the client
in the put command line.
- "JOB_TOO_BIG\r\n" The client has requested to put a job with a body larger
than max-job-size bytes.
- "DRAINING\r\n" This means that the server has been put into "drain mode"
and is no longer accepting new jobs. The client should try another server
or disconnect and try again later.

/*
Put a job.
It inserts a job into the client's currently used tube.
data is job body.
pri is an integer < 2**32. Jobs with smaller priority values will be
scheduled before jobs with larger priorities. The most urgent priority is 0;
the least urgent priority is 4,294,967,295.
delay is time to wait before putting the job in
the ready queue. The job will be in the "delayed" state during this time.
ttr -- time to run -- is time to allow a worker
to run this job. This time is counted from the moment a worker reserves
this job. If the worker does not delete, release, or bury the job within
ttr time, the job will time out and the server will release the job.
The minimum ttr is 1 second. If the client sends 0 second, the server will silently
increase the ttr to 1 second
