Hi again,

Having played with the task for a little while,  I am no longer sure
it completely justifies the effort involved.
The reason being the task requires modifying the buffer pool in one
way or the other, which implies
(a) significant effort on performance testing and
(b) changes in the buffer pool interfaces that community might not
welcome just to get 1-2 extra statistics numbers.

Any ideas ?

Regards,
Sergey
