Roy Marples	11a06bb9b1	If there are no file actions or dangerous attributes then use ... vfork(2) instead of fork(2) in our compat posix_spawn(3) function.	2014-02-21 15:51:42 +00:00

Roy Marples	5c08c0c4ca	Replace poll(2) with pselect(2) and vfork(2)+execve(2) with ... posix_spawn(3). Now we block all our signals at startup and allow pselect to unblock them for the duration of the call. This allows us to manage interrupts in a fashion to guarantee a consistent internal state. I have added a posix_spawn compat shim for systems that lack that call. pselect(2) has been supported on target for some time so there is no need for a compat shim there.	2012-11-10 16:38:52 +00:00
