 Replying to [comment:4 atagar]:
 > Gotcha. Figured this was the case. I asked because I suspect checking
 the executing thread (rather than de-registering signals) will be a
 cleaner approach and I was unsure how you exercised that part of the
 patch.

 Our priority is fixing Tor's CI, and we need this patch to find out why
 test-stem is failing.

 Can you merge this patch as-is, and fix it later?
 Or can you merge this patch without the parts that disable signals, and
 add them later?
