[vdr] 1.5.x Shutdown

Hi there,

I recently updated from VDR 1.4.6 to 1.5.2. (with no problems so far, by the way :)) But today I noticed something which seems to me like a small bug in vdr's shutdown routines. My shutdown script checks for different running processes (or connections) and does not quit vdr if at least one of the tests returns true. But since 1.5.2 (or probably since 1.5.0) the shutdown script remains as a zombie in such cases until vdr actually quits.

I haven't checked the sources yet, but I guess there's somewhere a call to close() (or pclose()) for the opened pipe(s) missing.
