Yes, but would you point every single developer on this issue?
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.
It is enough to let VDR set this flag on its own file handles - the main problem is that while an external script/program is running and because of inherited DVB handles - zapping is blocked - a restart of VDR is impossible.
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.
Whatever - if you don't see the point I cannot help.
