I am using LibSQLite3.0.dylib in a multi thread app.

After some research it would appear that libsqlite must be compiled
with the THREADSAFE flag set to 1 in order to support multithread
access. It also implied that UNIX distributions may have this set to
0 by default.
So... first - is the library included with Tiger THREADSAFE on or off
? My results suggest not.
The version included with Tiger was built with --enable-threadsafe.
You can see this at

Makefile>.
Hope this helps,
