[drmaa-wg] drmaa_wait() Clarification

[Daniel Templeton]

How is an implementation supposed to handle the case where two threads 
call drmaa_wait() on the same job id?  The choices are:

a) Both get notified when the job ends and both gets copies of the job 
exit and resource usage information
b) Both get notified when the job ends.  One gets the job exit and 
resource information and the other gets a DRMAA_ERRNO_NO_RUSAGE.
c) Both get notified when the job ends.  Which gets a copy of the job 
exit and resource information and which gets a DRMAA_ERRNO_NO_RUSAGE 
depends on which thread runs when.
d) That's not allowed

b and c are race conditions and there's no error code to represent d, so 
that leaves us with a.  This conclusion, however, needs to be clearly 
stated in the spec.  I believe the current SGE implementation implements c.
