windows tcp-server shared db among threads

Description (last modified by Richard Boulton)

From Richard on xapian-devel:

I'm not sure what happens for the windows variant of the server (which is a threaded implementation), but I imagine that there the same instance of the database is accessed by each connection: if this is correct, there are likely to be other problems since the database is not safe for concurrent access. A threaded implementation needs to create a new instance of the database for each thread.

I think that this bug, if indeed it is as I imagine, will cause undefined behaviour due to race conditions under load on windows, and should therefore be fixed for 1.0.0. Setting to block #118.

Fixing the first part of bug 141 fixes this too AIUI (and we have a first cut of a patch for that attached to bug 141).
