That's why I started to complain in this thread. Engine must have
as little global things as possible. What if during development of
the next engine version everybody forget to change name of this
global area? Wouldn't it be shared between two different engines?..
Besides, there are things that Y-valve can count itself without
bothering engines: it has full information about connections,
transactions, queries and so on.

But it should implement fb_engine_info() call which has no
considerable differences from SAPI.

Do you mean that fb_engine_info() can be called from remote site?
Just some minutes back you stated the opposite.
