This logic was added temporarily for testing gnats slurm/223.

Avoid sending TASKS=0 to Wiki; Maui silently rejects the job (insofar as Maui silently does anything)

sets new environment variable SLURM_CPUS_ON_NODE for use by LAM/MPI.
Also fixed bug in srun task distribution logic for block distribution
in heterogeneous cluster.

gracefully kill all jobs allocated resources on those nodes,
gracefully kill all pending jobs that require those nodes,
leave pending jobs that exclude those nodes but ignore those nodes.
Added "best_effort" argument to node_name2bitmap() function.
Fix potential memory leak when maui scheduler interface resets
the required nodes.

terminating (without no-kill option) or just flagging the I/O streams
from that node as being done (with no-kill option).

Otherwise signal all steps associated with the job (unless individual job
steps are identified).

signals all job steps, but not the job script itself).

Allocate calls were using job table info in place after freeing mutex.
New logic copies data structures, frees mutex, sends message, and
then frees memory allocated for copy.

with SIGCONT.

requests can get backed up in a queue while the job actually completes).

   - fixes to help ensure slurmd uses the same key for shared memory
     on a restart (to avoid losing track of jobs)
   - slurmd only runs one launch thread at a time
   - fix bug in slurmd where multiple threads used same address space
     for connecting client address.
   - srun always sends SIGKILL to job step before issuing complete request
   - Changed short string for draining nodes to drng from drain.
   - srun default launch message timeout increased to 5s.

some problems with slurmctld communication hangs.

re-opening it for every write. Moving the log file generates a
SIGHUP, which triggers a re-open anyway.

away at any time anyway.

queued allocation request is satisfied. Srun just has a stub to catch
and log the message while using polling to notice the allocation has
been made.

 o Modify srun(1) man page to reflect that, really, slurmd debug level
   is only allowed to be set up to 4.

Change clamp test for opt.slurmd_debug to use LOG_LEVEL_DEBUG3 as the upper limit.  This seems to be what's intended by the man page.
