A python program with the following fragment...
try:
import psyco # a specializing [runtime] compiler
have_psyco = True # for 32-bit compilations of Python
print 'psyco enabled'
except:
have_psyco = False
should have failed and have_psyco set to False. It wasn't. Instead a module named "psyco" was created with a single element "__name__" set to "psyco". Later a conditioned dependency based on have_psyco being True caused a crash.
The same program ran just fine after the offending psyco-based statements were commented out.

I can't reproduce this. What does print psyco.__file__ show you? My guess is you have a psyco.py file somewhere in your sys.path that is being picked up when you aren't expecting it to be

Sorry, I hit send prematurely.
I'm preparing a more definitive scenario.

Hmmmm... Good thought so I took an extensive look at PATH and sys.path. No Joy.
Looking then at CLASSPATH I see I had it defined to be ".:..:" ...a leftover artifact from some testing I did a year or two ago. When I removed ".." (parent dir) everything worked as expected.
What's curious is the parent dir is a dir of [uninteresting] dirs. So then how could Java/Jython pick up anything related to psyco with just ".."?
...unless Jython sets/resets the working directory for some reason and the parent dir at that point has a file with psyco in it. (I do have such files in various places in my file system but none should be "interesting".)
For now I can get along with CLASSPATH=. but if I or anybody else were to use a relative pathname in their CLASSPATH they could conceivably get unexpected results? Dunno, just a theory.
So thank you Philip for the hint. I'm good-to-go, but this does raise the question: Does Jython/Java change working dirs (internally/on-the-fly) and then use CLASSPATH from that point making relative paths problematic?
