Bug Description
By someone's braindead decision popen() is implemented via fork() and thus requires as much memory as used by parent process to start a new program (which has nothing to do with the parent).
Given that mysqld is normally configured to occupy as much RAM as possible this leads to unjustified memory and swap requirements just to enable mysqld to run helper scripts.
