New submission from Mattias Engdegård <[EMAIL PROTECTED]>:
If the stdin/out file descriptors are too large to be used with
select(), subprocess will fail in .communicate(). Example:
# raise the fd limit to something like 2048 before running this
import subprocess
somefiles = [open("/etc/passwd") for i in xrange(2000)]
print subprocess.Popen(["date"], stdout=subprocess.PIPE).communicate()
The solution would be to use select.poll() in subprocess instead.
