We should add support for finding resource leaks in regrtest. We can take advantage of existing support for this: -l (findleaks), -R (huntlrleaks), which are explicitly disabled for Jython in the current version.

Two things we can do:

1. Check for growing number of open files with lsof on platforms where this is supported, after each test is run. (There may be a Windows equivalent as well). We can also look at adding support for classloader leaks.

2. Check for garbage leaks using the support for gc debugging available as of 2.7.0.

This should be very helpful stabilization for 2.7.2.
