The server never sees the names - they're translated into handles.
If, however, several threads use the same names, they may be
referencing the same handles, which will cause problems.

Gpre predates threads in general - it's the oldest part of the product,
older even than the engine. I suggest that you look at the output
of gpre, looking particularly at the attach, start_transaction, and
compile_request calls and the handles they use. Be sure those handles
are thread-specific and things should work.... Famous last words...
