### Release 3.1: log file pre-allocation

This change only affects Win/32 applications.

On Win/32 platforms Berkeley DB no longer pre-allocates log files. The problem was a noticeable performance spike as each log file was created. To turn this feature back on, search for the flag DB_OSO_LOG in the source file log/log_put.c and make the change described there, or contact Sleepycat Software for assistance.
