I committed your cleanup patches fro test/* and warning
removal for strace.c, but this one has slight problem:

patching file process.c
Hunk #3 FAILED at 3020.
Hunk #4 FAILED at 3114.
Hunk #5 FAILED at 3130.
3 out of 5 hunks FAILED -- saving rejects to file process.c.rej

Care to rediff against current cvs?

You may want to use do_ptrace() if you want to get
ptrace errors reported here.
