That seemed to be fixed already, at least I never saw that error since 
upgrading to 6.5.6.

Haven't seen that one yet, maybe I've not run quite the magical number 
of jobs yet.

Yep, remember that one, I've got around it by installing the executables 
on a UFS partition.
Everything else seems to work flawlessly, indeed; the full MPI testsuite 
completes without errors, and I've even run the extra LAM tests from the 
6.6-beta with partial success.
One thing to consider when running jobs across multiple machines is 
MacOS X's awkward NFS naming scheme.
Thanks for the great work!
