Here, with only Scheme code, `dynamic-wind' should do the job.

In the AutoGen case, where C code is involved, that might be necessary.
OTOH, the AutoGen folks might as well be able to use `dynamic-wind', who
knows?  :-)

(I tend to be reluctant to adding such a thing because it looks
fragile.)

Thanks,
