+	- cygwin unfortunately patches the stack at runtime, so we use the pthreads
+          backend, which is an order of magnitutde slower. unfortunately, cygwins
+          pthread implementation isn't very complete either, so allocate the stack
+          twice just to be sure.
+          (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
+          in its ithreaded perl - best recompile cygwin and use the 'w'indows
+          backend for much better performance. also disable ithreads for
+          even better performance...).
