More like "unjustifiable for a single port" than impractical.

The second approach is more or less what I'm doing myself on a private port.
However, the code for this simply would not integrate cleanly with the
existing source base. What would is use of the __declspec(thread) directive,
which could be macro'd into the definition of each global var under Win32.
This, with some other related changes, would bring a Win32 multi-threaded
port into existence in short order, however is not (yet) supported under the
MingW environment.
Cheers,
Claudio
