Following thread test failed after(include) build 80 on solsparc/solx86
platform. It still pass on Linux platform with b83.

misc/threads/ThreadInterruptTest3 execute_positive ThreadInterruptTest3

Here is command line to run the tests with b79 and b80.
You will see the different behavior if you compare the running speed and
test output generated by b79/b80.

$ /net/jdk/export/disk6/promoted/jdk/1.4/beta3/b79/binaries/solsparc/bin/java ThreadInterruptTest3

$ /net/jdk/export/disk6/promoted/jdk/1.4/beta3/b80/binaries/solsparc/bin/java ThreadInterruptTest3

Two threads taking turns interrupting 1000 times to each other.
But with build 80 and after, it run much slower.
