Ok -- finally getting around to tracking this down again.

Ok -- attached is the end of the strace from 'strace -f bpsh 7
/usr/java/j2sdk1.4.1_01/bin/java -version'. There are some calls to
SYS_223, which I am guessing is the bproc syscall. I am going to attempt
to decipher those calls a bit, but I would appreciate any help you may
have on this one.

Thanks!
