Indeed, my hunch is that dbd_oracle is NOT thread-safe.

I don't know what's causing it, so I can't create a small snippet
of code to reproduce it.

Once I have a reproducible test case, I'll provide it.

In the meanwhile, can anyone give me any pointers as to how to
do root cause analysis for this kind of problem?  Are there good
functions in the core to breakpoint?  Otherwise, I'll just have
to keep stepping through the GC code and inspect before and after
of all the variables (ouch!) to see what code is corrupting what.
That'll suck ...
