[issue1441] ptrace/gdb doesn't work after process blocks SIGTRAP

["Simon 'corecode' Schubert \(via DragonFly issue tracker\)" <sinknull@xxxxxxxxxxxxxxxxxxxxx>]

New submission from Simon 'corecode' Schubert <corecode@fs.ei.tum.de>:

If a process blocks SIGTRAP, an attached debugger will not be able to break again (same is true for SIGINT, for instance).

We should change the behavior so that the debugger will be able to see this signal, or to change how a ptrace'd process gets suspended on trap exceptions.
