Log Message:
Enhance reliability of ptrace(2) in a debuggee with multiple LWPs
Stop competing between threads which one emits event signal quicker and
overwriting the signal from another thread.
This fixes missed in action signals.
NetBSD truss can now report reliably all TRAP_SCE/SCX/etc events without
reports of missed ones.
This was one of the reasons why debuggee with multiple threads misbehaved
under a debugger.
