Davide Libenzi wrote this about his patch and concerning the small note
about breaking debuggers:
'If the "debugger" has a bolt-in rule to expect the instruction following
the INT# to be skipped, yes. As far as debuggers that are really used
goes, it did not break any of them. If this copy protection for example,
has a bolt-in instruction sequence that expect the instruction following
INT# to be skipped, than I believe they should code it better. Patch 1
does simply enable the debugger to see every instruction to the ptrace'r.
While before the instruction following INT# were silently skipped.'
