condition::wait() - Alertable in Win32

What is the latest thinking on making condition::wait() and 
condition::timed_wait() "alertable" in the Win32 environment?

Please consider this a "me too" request for such a feature!

I'm trying to implement a cross-platform (Unix, Windows) 
implementation of a Proactor pattern that manages asynchronous 
sockets.

It seems that the way to implement this pattern with as much code 
common to both platforms as possible is to use
1. Overlapped sockets that call back (not post messages) in Windows.
2. Signals in Unix (similar to the Windows call backs but with less-
clear semantics in my mind).

For this scheme to work, the wait functions need to be alertable in 
Windows, but the Unix system shouldn't need any changes.

>From the research that I have done so far, in my particular case, I 
would only need wait and timed_wait to be alertable, and it would be 
appropriate that they were always altertable - I would not need a 
way to enable or disable this feature.
