[issue1440] ptrace/gdb doesn't work after process blocks SIGTRAP

[Simon 'corecode' Schubert (via DragonFly issue tracker)]

New submission from Simon 'corecode' Schubert <corecode at 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.
