Oh, and for any kind of ptrace changes, please always run the whole
ptrace-tests suite before and after.  That is by no means an exhaustive
test that you haven't introduced new problems.  But if you introduce
regressions in that suite, it is quite like that you are causing problems
for existing ptrace users like gdb (even if some tests were racy before,
if the real-world practical results change, it could be a problem).

http://sourceware.org/systemtap/wiki/utrace/tests has the pointers.

Thanks,
Roland
