When you use AntCall it completely reparses the XML file into memory again, 
and it seems lax about releasing the memory afterwards. I don't know if 
this is due to retained references or a lazy garbage collector.

I have had multiple build scripts that go as high as 350M of memory - I had 
to split them to avoid overrunning virtual memory.

[Shameless self plug coming up]

One thing that helps is to avoid AntCall completely - in my case I achieved 
this by using some XSLT to generate parts of the build script.

Check out my post to ant-dev a couple of days ago entitled "Submission - 
Ant Templating" for some XSLT you could find useful. Note that you *don't* 
need to know XSLT to use this, my submission allows you to write the 
templates completely within your build file.
