Great to have you back! Thanks for your continued attention to the SRFI,
and sorry for slacking off myself.

One major thing left to clear up is working-directory. Gambit and Kawa
would strongly favor a per-thread CWD distinct from the OS process CWD.
Can we add language to the SRFI permitting implementations to use their
own idea of the CWD?

Kawa and Gambit also have the current directory as a parameter object.
This implies the getter doubles as the setter:

Gambit:
(current-directory)
(current-directory "/tmp")

Kawa:
(current-path)
(current-path "/tmp")

Kawa has distinct path datatype, so (current-path) returns a path object
instead of a string. The setter takes either a path or a string.

I can do a Gambit implementation (help is gratefully accepted).
