(sorry FX, I meant to reply to the list only)

Hi all, thanks for your quick responses.

After reading through the thread, it looks as if the LD_PRELOAD method
is the easiest and quickest to setup, so I'll try this for now.
However, when I've got my thesis out of the way (at last, probably by
the end of September) I might look at preparing a patch as you
describe above. It would be a learning experience for me at least.

Thanks for your help,
John
