"make -j _n_" hangs reproduceably in latest cygwin 1.3.3-2

Sigh, sad but true.

Consider this makefile which will create 50 independent targets, taking
one second elapsed for each file:

   files:=$(addsuffix .t,$(foreach j,0 1 2 3 4,$(foreach i,0 1 2 3 4 5 6 7 8 9,${j}${i})))

   .PHONY: test
   test: ${files}
   	@echo test complete

   .PHONY: clean
   clean:
   	rm -f ${files}

   %.t:
   	sleep 1
   	touch $@

If you run with "make -j10" this should complete in 5 seconds(-ish).
Unfortunately it invariably hangs on my machine (Dual PIII 733, Win2000)
after the second set of sleeps. Strangely, "make -j _n_" works for all
values of _n_ < 9.

Take out the sleep and it works fine.

Replace the sleep with some other dodgy delay,

   a=`date`; while [ x"$$a" = x"`date`" ]; do :; done

causes it to hang for different values of _n_.

Go back to the previous version of the cygwin dll, 1.3.2-1 and it works fine.
(uname -a: CYGWIN_NT-5.0 PANG 1.3.2(0.39/3/2) 2001-05-20 23:28 i686 unknown)

Hope this helps.
