Thanks for the feedback! Yes. It would be good to figure out how much 
memory a tasklet and a deferred use. However I was worried about how 
much more kernel memory is used up when one increases the descriptors. 
This info would be useful in helping me decide whether to use a small
or large memory model. I guess I'll wing it.

I will also assume it would be good to recompile Python?

Thanks for the advice, will do.
