Explicit > initialization of sa_flags allows us to lose the bzero. Hmm.. my experience on other systems suggests sigactions should be pre-bzeroed (or memset) for portability reasons. This is required on some OS's as there are hidden fields in there, and doesn't require modifying the whole tree when a new field is added or changed to struct sigaction. eg, on another system: struct sigaction { int sa_flags; void (*sa_handler)(); sigset_t sa_mask; int sa_resv[2]; }; The programmer can't be expected to know what local additions to sigaction an OS may have.
