Since the [ABCL/CLOS/XP work for SLIME][abcl-clos-xp] is taking longer than expected, I’ve [provided an implementation based on Alan’s code][posix-syscalls] that satisfies my concerns about maintaining some amount of sanity on how ABCL is structured internally.  

[abcl-clos-xp]: https://github.com/armedbear/abcl/pull/586

[posix-syscalls]: https://github.com/armedbear/abcl/pull/588

As always, I hope both Scott, Alan, and other users of the Bear find this useful and acceptable.
