Comment(by mario):

 Peter suggested taking a look at how scsh implements umask.  The API
 documentation for umask in scsh is
 http://www.scsh.net/docu/html/man-Z-H-4.html#node_sec_3.5

 As far as I understand, scsh's umask is thread-safe (i.e., threads can set
 different masks).

 The primitive for getting the current mask is implemented like Peter
 suggests:

 {{{
 (define (process-umask)
   (let ((m (set-process-umask 0)))
     (set-process-umask m)
     m))
 }}}
