[MacPerl] WaitNextEvent Memory Leak?

[Jerry LeVan <levan@eagle.eku.edu>]

Greetings,

I am trying to put a GUI on some perl scripts that I have
built... 

My first attempt is to simply ask for an input file name and
and output file name, then generate the output file from the
input file data.

The following code will set me up, but only if I don't dawdle...

If I open the "About this Mac" display to watch memory usage
and start the program, pick a couple of files and then just
sit there and do nothing I can watch the size bar for MacPerl
slowing creep up to the end of it's allocation and shortly
thereafter drop into MacsBug ;(

The problem gotta be in waitnextevent cuz that is where it's
sitting... This evil behavior occurs in 5.2.1a1 and 5.2.0r4

Any suggestions? Here is the code...
