I think he's concerned about overloading the backend--either I/O wait 
due to database access or filesystem access caused by deleting all the 
links, then re-creating them--causing problems with the backend's 
ability to write the recording and/or seek table and/or stream the 
recording to a frontend...

I think mythlink.pl is still low-resource enough that it shouldn't be an 
issue, though.  (It seemed to be even on my old Athlon XP 1700+ 
backend.  I haven't had a problem since we removed the code from the 
bindings that "played" every recording with mplayer to get video 
information.)  Please let us know if that's not the case on your system.
