Didn't want to steal the other thread so started this one.

This work unit was running for 2.2 days before I noticed it. It was only running on 0.46 of a core instead of the normal 4 threads. Wasn't making much progress and had sent BOINC into panic mode. I aborted it as it looked like wasn't behaving correctly.

01:27:09 (3159): /usr/bin/flock exited; CPU time 20.859432
01:27:09 (3159): wrapper: running ./qmml3/bin/python (run.py)
malloc_consolidate(): invalid chunk size


Edit.. Just checked, looks like it got sent out again and complete correctly. Wonder what happen to cause it to not use all 4 threads.
