_Not_ uClinux, right?  I.e., your processor has a MMU, doesn't it?

What version (or date you got it from CVS) of uClibc are you using?

Can you run `strace' on the process (you'd better get rid of the call
to `write' first, so the strace log doesn't fill up with calls to


Would you like fries with that?
