* avoid cancellation in pcloseRich Felker2012-06-201-3/+4
| | | | | | | | | | | | | | at the point pclose might receive and act on cancellation, it has already invalidated the FILE passed to it. thus, per musl's QOI guarantees about cancellation and resource allocation/deallocation, it's not a candidate for cancellation. if it were required to be a cancellation point by posix, we would have to switch the order of deallocation, but somehow still close the pipe in order to trigger the child process to exit. i looked into doing this, but the logic gets ugly, and i'm not sure the semantics are conformant, so i'd rather just leave it alone unless there's a need to change it.
