[Zope-dev] Unexpected IOError / print in external Product class

[Robert Thomson]

Just recently my Zope instance started giving IOErrors when using "print"
from a custom Product.. we've been using print for debugging purposes and
up until now, this has worked well..

It doesn't IOError every time, though.. in fact, it appears to only IOError
every second time when it hits print... so a page reload will
succeed.

At the moment I'm baffled, and am assuming it's a strange zope
occurance which I hope someone else has encountered before, and
solved.

Zope version is 2.5.0.

Cheers,
    Rob
