So this is probably too expensive of a cost for every process exit.
The problem is that the cost will be taken even if the process is
not a UMH.
I've taken my time to respond in hopes that I could come up with a
good alternative to suggest, but so far I don't have any better ideas.
I'll keep thinking about this some more, please let me know if you
have any ideas.
