These forms manipulate the effective user/group IDs. Possible values
for setting this resource are either the real user/group ID or the
saved set-user/group-ID. The \texttt{with-...} forms perform the ususal

effective user and group IDs are thread-local.

Scsh treats working directory, umask and environment as a thread-local

a thread is started: \texttt{spawn} assigns the initial values whereas
\texttt{fork-thread} adopts the values of its parent. Here is a
