Subject Re: Possible memory leak in FBCLIENT.DLL

Well, in fact it's not my fault. My Delphi programs are based on a
suite of DB access components that implements this "feature".

This suite (I think I can't mention its name 'cause it's commercial)
supports multiple database engines, so it loads the relevant DB client
library only when the first connection to the DB is made, 'cause only
then it knows to what DB engine I'm trying to connect to. When the
last connection is closed, the client library is released.

I use these components on an application server that connects and
disconnects from the DB when clients request data... so at every
client connection the DLL is loaded and unloaded, eating up a lot of
memory after thousands of connections.

I'm watching at the windows task manager to see the memory used by the
