Add a new feature to the test suite suggested by Icarus Sparry: set a timer before invoking a test, so that if it loops infinitely we will wake up and have a chance to kill the process and continue.

This test creates a makefile where all depends on three rules
|
|
which contain the same body. Each rule checks for the existence
|
|
of a temporary file; if it exists an error is generated. If it
|
|
doesn't exist then it is created, the rule sleeps, then deletes
|
|
the temp file again. Thus if any of the rules are run in
|
|
parallel the test will fail. When make is called in this test,
|
|
it is given the -l option with a value of 0.0001. This ensures
|
|
that the load will be above this number and make will therefore
|
|
decide that it cannot run more than one job even though -j 4 was
|
|
also specified on the command line.";
