gpg hangs

I am not sure why it hangs, since I have a lot of entropy.

$ cat /proc/sys/kernel/random/entropy_avail
4096

The solution worked for me is "Ctrl-z" then type "fg".  I do not know why suspend then restart it would make a difference.  This is on Centos 5.

This is a workaround rather than a permanent fix.

using strace on it also wakes it up.
