There are core dumps from runs where there is only 1 thread doing subversion
work (plus a thread collecting performance results and the master thread
just waits for the others). Look for "-N 1" in the command line for these
runs (I count 9 of them). Also, I still get failures if I build mstone
without threading.

It does fail faster when there are multiple worker threads. Each thread is
completely independent inside mstone (separate WC, memory pools, etc).
However, I don't know if the subversion libraries are sharing things. I
found out that openssl does this, but serf should be setting up the proper
openssl locking now.

I'll see about updating. The new neon/serf switching will require some work
before I can do comparison runs again.
