"witness_lock_list_get: witness exhausted"

[Peter Jeremy]

I'm getting the above message when running Peter Holm's stress
test with INCARNATIONS=150 on a 16-core sparc.  Does this mean
LOCK_CHILDCOUNT is too low or does it indicate a leak in witness
lock_list_entry's somewhere?

The comment on LOCK_CHILDCOUNT indicates it is dimensioned to
allow 2048 threads to hold 5 locks each but it's not clear how
many threads will get started at a given INCARNATIONS count.
