Well, you've got intermediate data structures in HSQL. In particular,
each column access must traverse an
allback into
Haskell, so they can all be imported unsafe for greater efficiency.
But it doesn't directly address threads, so I don't know what to make of
that. Do you have a reference?

This module builds atop the standar
Hello,
I'm pleased to announce the release of MissingH 0.7.2, available from
