This didn't fix the issue. It's not a matter of adjusting timeout values.

However, I believe I've resolved the matter, more or less. You see, I think
the problem is with Gmail...

My Teapot application is using
ZdcSecureSMTPClient>>sendUsingGmailAccount:password:to:message:. For
whatever reason, Gmail is taking to long to respond.

In the main thread, timeout causes the network to report a timeout error to
the web browser. It seems that the Pharo application cannot capture this.

But if I fork a process to do the sendUsingGmailAccount function, Pharo does
capture this...a debug window opens with the timeout error message. The
debug window tells me that it's timing out on waiting for data on the

Fortunately, the debug window does not prevent the Pharo application from
continuing normally. So I can live with this.

The alternative is to NOT use Gmail as a SMTP relay and *manually* send
emails to my recipients. However, this would be extremely tedious and

I'll play it by ear. If the timeouts and debug windows prove to be
problematic, I can fall back on manual emailing. Such is life in the world
of networking.
