I think the attachments were stripped out, may be by the mailing list
itself.  I had them as attachments since I was worried that gmail will
damage white-space if I did it inline.

Is there a standard way of submitting patches to the list? For now I
have the patches at:
 http://sites.google.com/site/cjayachandran/files (the files are
ptrace.S.patch and gdb.patch)

Thanks,
