I haven't been able to find a sane way of avoiding the hang on exit 
on Linux or Solaris. OpenBSD doesn't seem to have the problem - there 
seem to be some differing fd semantics as work. Anyone who want to try
to fix the problem would be well advised to investigate these differing
semantics.

By 'sane', I mean a solution that won't lose data even under pathological
conditions. An avoidable hang on exit is an annoyance, data loss is 
unforgivable.
