Kyle Evans c34a5f16fa posix_spawn(3): handle potential signal issues with vfork ... Described in [1], signal handlers running in a vfork child have opportunities to corrupt the parent's state. Address this by adding a new rfork(2) flag, RFSPAWN, that has vfork(2) semantics but also resets signal handlers in the child during creation. x86 uses rfork_thread(3) instead of a direct rfork(2) because rfork with RFMEM/RFSPAWN cannot work when the return address is stored on the stack -- further information about this problem is described under RFMEM in the rfork(2) man page. Addressing this has been identified as a prerequisite to using posix_spawn in subprocess on FreeBSD [2].
