[erlang-bugs] Bug in the resolver?

Actually it might be a bug. There's a clause in do_udp_recv/4 that will call
do_upd_recv/5 with the value of Then as undefined.
If this value passed to now_ms/2 , it will crash. The crash reason is
converted to case_clause instead of function_clause because now_ms/2 is
inlined.
