syswrite should downgrade automatically. if it does not, thats a bug in
perl. however, this is a red herring.

There are lots of bugs that can result in this behaviour. The best way is
indeed to fix them.

However, the stroy has a problem: the behaviour of lingerign and normal
writes is the same, so this behaviour cannot be related to DESTROY.

Most likely this is simply caused by a push_write writing non-octet data,
and the next write will cause problems, regardless of DESTROY.

Definitely.

As I said, the DESTROY and lingering don't treat your data differently,
and there are many usage bugs that result in bad behaviour.
