> Abseil claims to have a async-signal-safe spinlock class:
> https://github.com/abseil/abseil-cpp/blob/master/absl/base/internal/spinlock.h
> This could be used to implement rudimentary mutual exclusion between a signal handler and regular code that sets up or tears down shared resources used by the handler.
> The caveat is that signals need (apparently) to be blocked inside the handler before taking the spinlock.
