Plugins can call SystemExec() just as well when the want to execute
an external program.

IMHO it is no feasible solution to expect every file handle to
be opened with FD_CLOEXEC. Even if VDR itself would do this, there
could still be plugins that don't.

I'd say if some plugin wants to run an external program, it needs
to take care by itself that all unneeded file handles are closed.
That's what SystemExec() is for.
