You will encounter a possible problem on main thread termination.
Normally it's done automatically in static ~this(): a linkDead message is sent 
to all spawned threads listed in "links" and then close() is called on the mbox. 
Those linkDead messages have thisTid as sender and that's a problem, because 
with custom mailbox thisTid != ownerTid, so the child won't treat that message 
as OwnerTerminated. It's caused by "links" being global and populated by 
spawn(). And if you make your own spawn, that doesn't touch links, the child 
won't be informed about parent's sudden death. How do you work around that?
