[JWplugins] Memory leak tests

[Jari Williamsson]

Hello all!

As you might now, my plug-ins are based on my own PDK Framework (which 
gives me a much nicer programming environment than doing the C++ 
development directly towards the Finale PDK).

However, since I started with the PDK Framework 2.5 years ago, my main 
focus has been to create new plug-ins and add more functionality. And at 
the start, my plug-in projects were quite small, and hunting for "tiny" 
memory leaks in the plug-ins was not worth the time.

Since then, the plug-in projects has grown quite considerably in size 
and complexity, and the demands for real memory leak testing has become 
more and more important. (A memory leak of 20 bytes is "nothing", but if 
that code is executed 1,000nds of times during the plug-in processing, 
it will at some point start to hurt performance.)

Yesterday, I started to do proper tests of the plug-ins for memory leaks 
and I have found some places both in the PDK Framework and in the 
plug-ins that I have now fixed. All plug-in updates that appear from now 
on should be properly tested for memory leaks (meaning better overall 
stability if you use the plug-ins many many many times without 
restarting Finale).


Best regards,
