Thanks, this is a real bug and is being fixed. (The timestamping code
in sock.c already has it right.)

This is user-mode code, should use u_int32_t (uint32_t?) (but I should
verify that this type is actually available in _all_ major versions of
the C library; it's in my work queue now).

Most of these are only used internally; it is harmless for them to get
bigger, e.g. flag sets. "sockshost" is an exception since it's an IP
address, _but_ the places where it's declared unsigned long are the
ioctl structures which get included by both kernel and user mode
stuff, and we can't use __u32 in user mode. The really correct
declaration here would be struct sockaddr_in (ouch).

Any "timeout" stuff counting jiffies has to be long AFAICT, see
<linux/sched.h>.

This must actually be unsigned long on any architecture, see
<asm-alpha/spinlock.h> and <asm-alpha/system.h>.
