Subject: Unalias with-absolutely-no-interrupts in runtime/prgcop.scm.
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=9a2b5d817cb4593d18c9c9474bae7bcc6ffa0ded;p=mit-scheme.git

Unalias with-absolutely-no-interrupts in runtime/prgcop.scm.

It is not atomic in multiprocessing worlds.  The alias "atomically" is
no longer appropriate.
