IDE drive or SCSI?  I see this all the time when accessing my IDE
drive.  The only suggestions I have are either to just wait and let
MacPerl do its thing. or try to switch MacPerl to the background
*immediately* after starting the script.  Maybe a sleep at the
beginning would allow you to do this.  Moving it to the background
will slow the script down tremendously, but will allow you to do other
things on the machine.

} One possibility is calling sleep every 10 directories or so, but
} this seems pretty hokey and would slow the script down quite a bit.

If this were Unix, you wouldn't have this problem.  I don't know of
any way of messing with MacOS scheduling aside from a vague
recollection that a ResEdit hack might do it.  If so, someone must
have written a program to make it easier to do.
