[torqueusers] can't run jobs over 62 nodes 2ppn on OS X

[Glen Beane]

I get Invalid argument errors in open_demux, every time I try to start 
a job using more than 62 nodes

I noticed that sysconf(_SC_OPEN_MAX) always returns 255 on my apples.  
I hacked mpiexec and pbs_demux to use 1024 instead of what is returned 
by sysconf(_SC_OPEN_MAX) always returns 255 but that didn't help.

Does anyone have any ideas?
