oh, right, i did only one eighth to check and see if it was scaling
near linearly, as i couldn't even run profiling without python dying.
i have 400mb ram and 2ghz processor, on freebsd, so it shouldn't be
performance. i'll try your suggestions and see how it works.

In fact, as one of the Peter's (either Otten or Hansen) explained to me,
for line in open(file):
is actually both faster (being buffered) and generally better for very
large files because it doesn't read the whole file into memory, like
readlines does (if you have a memory limitation).

the line of your example raise another question: opened file will be
read at once time, as method readlines() do, or it will be read line by
line as method readline() do.
It will be read line by line as readline() does.

I think Kent Johnson is longer, but a bit faster...

This is a good place to use 'get' method of dict:
frequency[word] = frequency.get(word,0) + 1
