Me, Mike and Dmitry discussed this on IRC and came up with the following
two approaches to implementing it.

The first, which is probably the simplest, is just to send a signal to the
program which then gets the pending thread creation info from the
wineserver and sets up the thread.

The second is to have some code at a magic location in memory placed
there by Wine beforehand. The caller of CreateRemoteThread then uses
ptrace to attach to the remote process and jump the main thread to that
code. In other words you literally take control of a pre-existing thread
and make it to your bidding.

The signal approach is probably easiest. I originally thought signal
stacks were too small to do anything like wineserver RPCs on but Mike says
that isn't the case anymore, so it's probably the nicest way to implement.

In theory it shouldn't even be too hard. A nice project for somebody
interested in the lower levels :)
