[openib-general] Re[PATCH] Opensm - clean exit on ^C

[Yael Kalka]

Hi Hal,

I've noticed that sometimes when killing OpenSM using ^C not all
threads are killed.
The reason for that is that there are threads that mask the
signalling, and when removing the ^C handling from OpenSM, these
threads still mask the signalling and stay alive as a result.
The following patch fixes this.

Thanks,
Yael
