I experience the same problem but the above patch doesn't really
help me.  Without the sleeping time, I get failures with signature
checking of incoming emails almost always; with the sleeping time,
it works at least in 20% of the cases.  I increased the time to even
10 seconds but the success rate didn't increase further.  The
behaviour remains probabilistic.

All aspects of GPG interaction -- signature checking, signing and
encrypting -- are affected by this behaviour.

Tschö,
Torsten.
