core_sys_select	We can actually return ERESTARTSYS instead of EINTR, but I'd* like to be certain this leads to no problems. So I return* EINTR just for safety.* Update: ERESTARTSYS breaks at least the xview clock binary, so
compat_get_fd_set	Ooo, nasty. We need here to frob 32-bit unsigned longs to* 64-bit unsigned longs.
