Hi,

Thanks to John Elion for this contribution.

I have tried it on the Ant test cases. This makes the execution of the =
test cases shorter by 3 minutes with 2 threads [ not sure what is the =
total time because I also run the antunit tests ].

Some of our test cases do not support parallelism because they are =
creating and dropping temporary directories and files which have the =
same names.

this makes errors looking like this one :
    [junit] Testcase: =
testNoAddNewLine(org.apache.tools.ant.filters.NoNewLineTest):	Caused =
an ERROR
    [junit] Warning: Could not find file =
/Users/antoine/dev/asf/ant-core/src/etc/testcases/filters/result/nonl to =
copy.
    [junit] =
/Users/antoine/dev/asf/ant-core/src/etc/testcases/filters/build.xml:111: =
Warning: Could not find file =
/Users/antoine/dev/asf/ant-core/src/etc/testcases/filters/result/nonl to =
copy.
    [junit] 	at =
org.apache.tools.ant.taskdefs.Copy.copySingleFile(Copy.java:639)

Does someone have a suggestion about how to adapt the test cases to =
support parallelism.

I was thinking of adding somewhere in the Ant codebase a utility class =
or method to get the PID of the currently running process
and add the PID somewhere in the name of temporary folders created for =
tests.

Any thoughts on that ?=20
