Resending to Larry and the test-results list to CC bug-cvs for input on
the potential sanity.sh changes and the portability of `dd'.

Hrm.  Larry, could you provide a little more information about this
failure?  If you back out the most recent change to zlib.c, does this
test pass on BSDI & AIX?  Also, what, exactly, is causing the "memory
exhausted" error?  Is it a new bug or simply because the test attempts
to commit a file of about 4MB in size and the whole thing is held in
memory at once (twice? more? - client & server?)?

If it's the latter, I can think of two compromises.  The first is to try
and add infrastructure to SKIP this test if it returns "memory
exhausted".  The second, and the one I think I prefer, is to SKIP this
test when dd and /dev/urandom are not available and otherwise use dd to
copy 20k from /dev/urandom into the file, which should make it mostly
uncompressable.  Is there a more portable way than dd to copy a set
number of bytes from one file to another?

(Hrm, I suppose I could generate the 20k uncompressable file once and
distribute it as test data, but that would mean either setting a
precedent with the first external test source for sanity.sh or adding a
20k uncompressable uuencoded here-doc to sanity.sh internally.)

Regards,

Derek
