I find that it often takes too long too...

Experimental patch (compile-tested only) attached. It adjusts the removal
check scheduling so that removal occurs at (by default) 6 minutes after
deletion. There is a 1-minute minimum delay, and the delay is reset every
time a recording is marked for deletion.

This also gives you enough time to unmark a recording, either by renaming it
manually or by using an undelete plugin.
