I don't yet feel confident about concluding anything from the problem
not occuring under windows because:

1) There is more memory on the citrix server that I tried the test on
under windows.
2) The full tests can't be run under windows (at the moment)
3) There was no problem under Linux two weeks ago, and I have yet to
work out what might have changed.

How soon could you change gec to raise "no more memory"? I would think
its definietly worth trying to confirm that this is what is happening.

I'll keep trying things.
