Not at all.

Actually I implemented them for me the way you suggested.

A few minutes ago I noticed, that this implementation does not exactly
the job I want them to.  Dunno yet, why (busy with business demands);
it's mostly the same code, which passed the test when patched into
chicken core.

Maybe that error is due to me not being familiar enough with the chicken
environment.  Overwriting make-parameter seems to be easy enough.  But
parameterize is a macro, linking to code, which was compiled with the
unmodified parameterize is IMHO bound to create subtile bugs.

But before I continue, I rather ask again to clear my confusion: are
dynamic-wind pre/post-thunks by chicken executed upon each thread
switch?

Thanks a lot
