It seems when I push signatureWithObjCTypes: hard - i.e. submitting
about 250 tasks into NSOperationQueue, signatureWithObjCTypes will
occasionally crash.
By occasionally, I mean about 1 time in 10 to about 1 time in 15 on a
dual core machine:

Familiar to anyone? I guess my next step is to try to check the input
very carefully.
