Очень говорящее название...

1) How it works
We have one Wine on the host in 64-bit only mode and two
on the guest side for 64-bit and 32-bit. Inbetween sits
a modified version of Qemu that runs the x86(_64) code.
To glue it all together there are thunks, lots of them
handwritten to understand in which situation a pointer
is valid and in which situation it could point to a
random address and should be ignored, and how to handle
writes to resulting structures in case of errors etc.


З.Ы. (Замечу Ышо): "hangover" обычно переводят как "похмелье",
но более точным является слово "бодун" или даже "бодунище" :-)
