?The observation in t?hat issue that tkinter and threads should be handled
in specific ways is certainly a given for old hands, who have long put the
GUI code in one thread with one or more concurrent worker threads typically
communicating through queues. But I haven't built anything like that
recently, so I couldn't say how helpful the current documenation might be.

The 2.x bug also shows in 3.x if it's linked with a nonthreaded version of

that much indication that its absence had failed to produce responses,
though they may not have been the responses you wanted.

Unfortunately the developers are rather too used to this kind of gratuitous
abuse and so many of them may have overlooked your detailed analysis of the
issues you were experiencing, since constructive contributions don't
normally accompany such rants.

The module being abandoned and unused is truly the only explanation I could

?tkinter's relatively small user base, perhaps amplified by dwindling
availability of "GYU in one thread" lore. Anyway they have certainly
clanged now.

?I wouldn't presume to tell Guido his job, given that I've never done it
and wouldn't be capable of it. Do you want the ??5 opinion poll or the ?10
opinion poll?

Let's hope nobody here wants an argument ;-)
