What become up 'set maxuprc=256'?  I thought that made it work.  Could
other people try it or has it been disproven?

This would hide problems during the test phase which would reappear in the
production phase, no?

Unfortunately, it's not possible to detect this globally, only when you're
actually parsing the schedule file and encouter a parallel group.  This
would mean running some tests this way and some tests another way.  That
might not be the worst of ideas, but it should be done on all platforms
then.  Additionally, it don't think it will really fix things, because
some tests that failed were not in a parallel group (and I firmly recall
that some of those were *not* follow-up failures).  I think it is more
related to a "high load" situation.


If I were a Solaris user and had a bit more insight into this problem I
would probably vote for #undef HAVE_UNIX_SOCKETS.  But I'm not...
