Public bug reported:
The python-dnspython package (most specifically, dns/resolver.py at line
25-29) uses /dev/random to get random data. I observed that this blocks
on /some/ machines that have Ubuntu 10.04 installed. It does not seem to
happen on older versions. This causes the import of dns.entropy to block
most of the time (but not always).
The solution is to use /dev/urandom instead. Two possible ways to solve this
problem:
1. Provide a 1.8.0 package in the main repositories - it seems to have the bug
fixed and is a maintenance release according to the homepage
2. replace '/dev/random' with '/dev/urandom' in entropy.py, line 25. I tested
this solution and it no longer causes the import to block.
** Affects: dnspython (Ubuntu)

dnspython-1.7* uses /dev/random which might block on lucid
