pyEctor think time increases with every new sentence

What steps will reproduce the problem?
1. Enter like 30-40 sentences, chatting with pyEctor
2. Observe response time and CPU usage

What is the expected output? What do you see instead?
Almost instant reply. That is, no more that 1 second to be reasonable.
I wait, with every new sentence, 10 second, 20 seconds and more...
@cleanstate does not help.

True.

That has always been the trouble with ECTOR: the more nodes there are, the more 
time
the reply will take.

I already did optimize some things (in the initial PHP/MySQL version), but 
there is
no miracle.

I can't compare reply times any more, as my Quad Core is much quicker.
It depends also on free memory, I think.

I initially wanted to use Google App Engine, and thus to use their persistence
mechanism, but this is not for today!

I prefer ending the development of expression parsing, to keep a clean and 
readable
algorithm the longest time.

And there is another trouble: I do not currently spend much time on pyECTOR 
(but your
feedback is a good motivation).

(please pardon my poor english)
