I'm a little concerned about the prospect of messing with signal handlers in
RunWithCapturedR, right before a release, since this runs during pretty much
all of the most used functions in Arrow (read/write CSV, feather, and query
engine after the user-defined functions PR merges).
Is there any chance I can convince you to allow registering a (thread-safe)
callback? I would love to be able to
`RegisterThreadSafeUserInterruptChecker([]() { SafeCallIntoR([]() { /* return
true or false */}); })` (but I understand if this is impossible or a bad idea
based on how this is implemented in Arrow C++.
