Before merging a fix for #112, I want to make sure that we can reproduce it and understand it.
In my opinion, the problem is not related to threading (as surmised in the original problem report), but is more directly attributable to file descriptor exhaustion and the difficulty in handling that gracefully. See misc/threading-tests/README.md in this PR for some demonstration cases.
My current inclination is to disable caching since that's the safest mode, and then work on reincorporating caching in a subsequent PR.
