 my patch is on my ftp and nobody works on it, but I mean it's good
begin for some next work. I not sure with implement this experimental
patch (but usable) to official sources. For example Jan has more complex
idea about query plan cache ... but first time we must solve some
sub-problems like memory management in shared memory that is transparently
for starndard routines like copy query plan ... and Tom isn't sure with
query cache in shared memory...etc. Too much queries, but less answers :-)
