A workaround for this bug in 0.91 (not closing a connection) is quite
straightforward (the bug will be fixed in 0.92), but as a next obstacle
there are some conflicts between the new use of file descriptors
in Net::Server 0.91 and the way file descriptors are assigned when
spawning external programs, both by amavisd itself and by SpamAssassin.
This is not a bug in Net::Server, just a compatibility issue.
The "Error closing main::stdin: Bad file descriptor" is just
a (trivially fixed) tip of the iceberg.

The fix is nontrivial, so my intention is to get the 2.4.0
out on the street pretty fast, and not to bother with preparing,
testing and releasing a patched 2.3.3. People that want to
stick with 2.3.3 should not upgrade Net::Server beyond 0.90,
which is the last version under which 2.3.3 works reliably
in all setups. Port maintainers are of course free to patch
older port if they so desire.
