pipes and popen2

[Stian Husemoen]

I was a bit bored this weekend, and passed time coding python. In one
snippet I wanted to make a UI to ispell. The idea was to create a
bidirectional pipe, keep that pipe open, and feed ispell with words to
spell. Like in this pseudo-code:

	stdout, stdin = popen2.popen2('ispell -a')
	
	for word in wordlist:
		# spell this
		stdin.write('pyhton')

		# result
		print stdin.readline()

Problem is popen2 wont give me any output until I close stdin. Is there any
way to both read and write to a program while keeping the pipe and
process open? I can't seem to find any postings or documentation on this
subject.
