Public bug reported:

when reading a 200mb csv file into the csv.reader 3 times in a row hangs 11.04 
linux completely. mouse not moving, fan 100%, the works.. 
except from the default 11.04 python packages i installed numpy and wxtools. i 
have a 8gb machine and sometimes the python process gets killed with an 'out of 
memory' error, but sometimes it hangs the machine. this happens more often when 
i have over half the memory in use before starting the csv import.
