I recently added thread-local variables to Anarki (last week or week before last, maybe). To use:

  (= foo (thread-local))
  (foo) ; read the variable
  (= (foo) 42) ; write the variable
Also, I've added semaphores to Anarki. If you want to wait on another thread:

  (let s (sema)
    ; thread you're waiting on
    (thread
      (sleep 1)
      (sema-post s))
    ; monitoring thread
    (sync s)
    (pr 'done))
As mentioned, Anarki only ^^

Looking at 'sync documentation, it would seem that you can also just call 'sync on a thread to wait for it to end.

  (let th
    ; thread you're waiting on
    (thread
      (sleep 1))
    ; monitoring thread
    (sync th)
    (pr 'done))

Thanks, that is exactly what I wanted. Although it might be nice to have a macro wrapper around 'thread-local for initializing variables

  (w/uniq void
    (mac w/thread-local (var (o val void))
      (if (is val void)
	  `(= ,var (thread-local))
	  `(do (= ,var (thread-local))
	       (= (,var) ,val)))))
then you could do

  (w/thread-local foo 0)
instead of the two step initialization

  (= foo (thread-local))
  (= (foo) 0)
