The regression test javax/imageio/stream/DeleteOnExit.sh has been failing in our
nightly runs as of 11/23/2005. That date corresponds to the putback of:
6299405: ImageInputStreamImpl still uses a finalize() which causes
         java.lang.OutOfMemoryError

The test fails with this message:
Files before test: 21
iis = javax.imageio.stream.FileCacheImageInputStream@e102dc
ios = javax.imageio.stream.FileCacheImageOutputStream@efd552
Files after test: 23
Test fails: tmp file exists!
