Asynchronous I/O on Windows is called "Overlapped I/O". It is a
bit involved to use though, especially since D by default
doesn't come with all the necessary headers. You can download
the win32 api bindings or you can just declare the bits as
needed.
My terminal emulator uses overlapped I/O and a spawned process
(and on Linux, it uses forkpty!) to talk to ssh on Windows.

I had to write a function to make an async pipe, then spawn a
process using them, then get and send data. I also declared all
the needed functions myself.
A lot of code to go through but it is a working example... a
few things to look for are MyCreatePipeEx, CreateProcess, the
word 'overlapped', ReadFileEx, and the simpledisplay.d library
it imports also uses SleepEx which lets other things trigger.
Thanks adam, this is very helpful!
