Close file handles in spawn()?

[Jonas K. <jon...@gm...>]

Hi CMUS developer(s),

while writing a CMUS plugin which posts track data to last.fm
and which is run via status_display_program, I noticed that spawn() does
not close file handles after forking (beside stdin), so the
status_display_program inherits all of them, including the file handle
of the audio device. This results in some kind of misbehavior, because
if the program takes some time to finish (as my plugin does) and if CMUS
exits in the meanwhile, the file handle of the audio device is still
open and can not be used by other programs.

Would it be possible to close at least the audio device file handle in
spawn() after forking? I would have written a patch myself, but I don't
really understand how that ops->close stuff works. ;)

Regards,
Jonas
