Memory issues, ideas?

Hello all, I have written script based on input from a csv that contains 4 lat, lon points per record. 
It works fine for quite a few features but attempting to run it over 100,000 or so it runs out of memory suggestions would be appreciated the 2 issues I have are below I only attached the part of the code that is having this issue:

1) it breaks on the featureList.append(polygon) at some large number of records...
If I could save and erase it each time without sacrificing to much speed would be ideal as I want to use it on even larger files.
I did attempt this before moving the copyfeatures up to the loop of lines but it increases the time too much 0.06s to 2.95 mins for 100 records.

2) I also would like to have the orginal .csv information joined to the shapefile/feature created but have not yet done this either based on the amount of time it takes to join the two together.

Maybe there is another way all together?
Thanks! :confused:
