We do prefer the POSIX way, which is to use sigsetjmp/siglongjmp, in which case we need no explicit unblocking of signals. It is only on non-POSIX systems without sigsetjmp that we use siggetmask. Non-Unix systems, such as VMS, should be handled like Windows are currently handled: by providing their own native implementation of highly non-portable routines such as run_with_timeout. That's the whole point of having an abstract run_with_timeout function.
