Attempt to fix permgen exhaustion on ci server.
Attempt to fix permgen exhaustion on ci server.

Buddy (Kalyan) mentioned today in the US/IN sync up (and previously via
email) that the head/springHibernateSpike build was failing on Hudson.
Hudson shows about 40 acceptance tests failing, with errors like

  com.thoughtworks.selenium.SeleniumException: Timed out after 30000ms

Strangely, the build passes (including all acceptance tests) on a
different Ubuntu box that Buddy and other TW folks are using. Buddy
mentioned their box is mostly similar: 32-bit Ubuntu 10.04 (lucid)--like
birch (ci.mifos.org)--except that they're using OpenJDK.

ci.mifos.org:~hudson/hudson-home/jobs/head-springHibernateSpike/workspace/acceptanceTests/target/logs/tomcat6x.out
had a ton of null bytes, then

  Exception in thread "main" java.lang.OutOfMemoryError: PermGen space
  Exception in thread "http-8083-75" java.lang.NullPointerException
  Exception in thread "http-8083-73" java.lang.OutOfMemoryError: PermGen space
  Exception in thread "http-8083-74" java.lang.OutOfMemoryError: PermGen space

Buddy, Jeff and I decided to try the following:

* bump up permanent generation space for the Tomcat VM used during
  acceptance tests
* if that doesn't work, experiment more on birch (ie: create a sandbox
  for running acceptance tests in /home/XXX, etc)

I recall the last time I tried running acceptance tests from /home/XXX
on birch, they ran very very slow for some reason I couldn't figure out.

The end.
