David Chase c6ee8e31e3 runtime: profiling on Darwin cannot use blocking reads 
On Darwin (and assume also on iOS but not sure), notetsleepg
cannot be called in a signal-handling context.  Avoid this
by disabling block reads on Darwin.

An alternate approach was to add "sigNote" with a pipe-based
implementation on Darwin, but that ultimately would have required
at least one more linkname between runtime and syscall to avoid
racing with fork and opening the pipe, so, not.

Fixes #61768.
