 Chicken currently doesn't provide bindings to {{{umask}}}(2).  It would be
 nice to have a procedure for that.

 Here's the proposed syntax and semantics:

 {{{(set-file-creation-mode-mask mask)}}}

 Returns the previous value of the file mode mask.

 {{{mask}}} can be specified using Unit posix's {{{perm/*}}} constants.

 Initial discussion on chicken-hackers proposes adding umask support to the
 posix unit.
