- No signal translation is needed. Our signals match the OSF/1 signals - an OSF/1 sigset_t is 64 bits. Make certain to use all 64-bits of it. We'd previously only used the lower 32 bits. This was mostly harmless as I don't know of an OSF/1 apps which use any signals > 31. However, the alpha Linux ABI uses the osf/1 signal routines and threaded linux apps tyically use signals 32 and 33 to comminicate with the manager thread, so it is important we preserve the upper 32-bits.
