Hmm, that might be something I hadn't actually tried.  And if I run it 
in a directory where I had previously run a multi-job check it doesn't 
blow up (maybe because the directory is already there?)  Due to the 
nature of my test program, I had to break with tradition and implement 
something akin to the test that generates random structs (I forgot what 
that one is called).  It ended up breaking the bastardized 
parallelization scheme, so I had to implement my own re-bastardized 
scheme.  Looks like I can just skip parallelization if 
GCC_RUNTEST_PARALLELIZE_DIR isn't defined.

I have another Solaris test issue on PR 80759 so I'll fix that along 
with it.

Thanks,
Daniel

PS: Oh! it might be due to the difference between -j1 and no -j argument.
