disclaimer: I haven't looked at the code, but my one question is
something that I'm not likely to figure out by reading the code diffs
anyway.

Is there a guaranteed scheduling of the reaper thread?  Is there any way
that it might get delayed long enough that other process manipulations
would fail due to the resources not yet released, and if so, can those
failures instead kick the reaper and try again?
