A slight variant on this idea would be to mask the variables themselves,
using macrology on a hash keyed on the threadID.

To illustrate:
MyProc->errType

would, on a threaded system, become something like:
((PGProc*)ThreadLocalHash(MyProc,GetCurrentThreadID()))->errType

I'm imagining that an approach like this would fit in very nicely with the
existing code. Not the most performance friendly solution however (and I'm
guessing that there might be a place or two where this might be important
:-).

Just a thought,
Claudio
