[Lldb-commits] 'process kill' is not working

Hello again.
Inserting some instrumentation on the debugserver's MachProcess::Kill() method, I get this:
1075 +0.000010 sec [5659/0303]: MachProcess::Kill() took 2002024 micro-seconds.
I'm having it consistently clocked at around 2 secs. Most of the time is spent in DoSIGSTOP.
Which makes sense, since we let our call to m_events.WaitForSetEvents() last for two secs.
This means that our default 1 sec timeout isn't working.
I suggest upping the timeout value from the default one second to 2.5 or maybe even 3, for the GDBRemoteCommunicationsClient. At least inside the GDBProcess::DoDestroy() call.
Regards,
Filipe
