I can't seem to find the error in my console history...  it had to do with
this line:

for (int i=0; i< SEM_COUNT; i++) {
               sem[i] = conn->semset->getValue(i);
}

Saying that "semset" is a private data member of that object.  I've already
rolled back my source code, but I can try it later after I'm done with the
cursor stuff.

Yeah, we usually have at most 5 statements allocated, but it's difficult to
force programmers to close stuff manually in a garbage collected
environment.  As a result, we have some pages that go crazy and allocate
hundreds, sometimes thousands of cursor objects.  The number of lines of
high level web code is so large, that it's just easier to handle this
management in lower layers.

I'm almost done with the patch, just a few things to clean up and I'll
attach it to an email to the list.

Thanks,
