Following firebird-devel and the Borland newsgroups (it is an
issue for InterBase < 7.1 as well), it seems to be an OS kernel
change regarding synchronization and/or the Mutex/Event/Semaphore
logic. Hope I quoted that right, because I'm a rookie in that
area. ;-)

I found one entry in the ChangeLog that might be directly related
to that:

* firebird2/src/jrd/: cch.cpp, jrd.h, vio.cpp:

Stripped implementation of events used by garbage_collection() &
cache_writer() procedures. This will fix known delay with
connecting/disconnect on at least WinXP. Also are the
connecting/disconnecting delays while debugging in MSVC6 gone.


I'm sure Dmitry, Nickolay, Arno, ... can be more of help here.
