Yes, i believe, but every time i run that script the memory usage of
zope( all processes ) grows up.
If the script was ended and zope grows up about 1MB would i think that
each request for the ZSQL Methods grows up zope
about 250K and 250K * 4 = 1MB.
My problem is that every time after running the script zope grows up.
Sometimes zope grows up about 1 or 2MB and sometimes only 100K, but zope
is growing up every time a run my test-script.

On our production server the last time zope grows up to 100MB in 6
hours, and maybe thats not so good.
