And I can confirm on Win XP SP3 with CVS, Audacity takes about 30 MB of 
memory once started. 

But the implication I got from the post was that 1.3.3 was not reacting
in this way to "Hear" running/having been running. Have you tried 1.3.3
to see if Audacity gulps ten times its normal memory in that situation?
If it doesn't, then there may be something to address if significant
numbers of Mac lovers use this plug-in.
