Hopefully, those tasks that don't terminate fail due to the same problem, so I'm going to investigate this issue further.

The fail, spin forever problems sounds a bit like you might be running into problems with either the timeout code or the posix semaphore-based wakeup mechanism. I had similar problems when initially working on the psem parts, and in particular ran into semantic issues with the interpretations of timeouts and relative vs. absolute time. There might be either underlying differences in how it works with libkqueue that need to be resolved, or there could be bugs in the psem code (I should out a few of them only a week or two ago once I made it through the last bits of the test suite).
