Details:

Running make-3.81rc1 with the attached makefile will hang if "-j 2" is
specified, but will run properly if "-j 1" is selected instead.  To
duplicate, put the attached makefile into a blank directory.  Running with
"touch test.0 && make -j 2" runs properly the first time and produces:

touch test.1
touch test.2
touch test.3
touch test.int
touch test.4
rm test.int

Running "touch test.0 && make -j 2" again hangs repeatably part-way through:

touch test.1
touch test.2

Running instead with "touch test.0 && make -j 1" repeatably produces the same
output as the first run.  Note that if "test.int" is touched externally, so
that's it's pre-existing, then "-j 2" works properly.  Deleting "test.int"
and retrying will hang.

I have reproduced this under both Windows and Unix, and on single and
dual-processor systems.
