Permissions describe who's allowed to use them, not when. IPC semaphores are a bit wordy, yes. But then, so is IPC shared mem.

NAME
IPC::Run::SafeHandles - Use IPC::Run and IPC::Run3 safely SYNOPSIS
use IPC::Run::SafeHandles; DESCRIPTION
IPC::Run and IPC::Run3 are both very upset when you try to use them under environments where you have STDOUT and/or STDERR tied to something else, such as under fastcgi. The module adds safe-guarding code when you call IPC::Run or IPC::Run3 under such environment to make sure it always works. If you intend to release your code to work under normal envionrment as well as under fastcgi, simply use this module after the "IPC" modules are loaded in your code. unimport When unimport, the original IPC::Run and/or IPC::Run3 functions are restored.
