No big news, just more evidence that this is a Windows specific problem:

- I've got RedHat 9 running on a 200MHz PPro w/128 MB ram. Works like a 
charm. :-)
- Downloaded the latest GCC 3.4
- ran configure + make
- gcj -static --main=Test -o test Test.java
- Ran ./test for ~1 hour. No GP or other visible problems.

I did run into something unexpected when I tried to run the test app from GDB 
under Linux, but thats probably just my limited linux skills... Or its most 
certainly something unrelated. The application recieves a "signal" as soon as I 
launch it.
