Brent,
My status is that I wrote a non-event based version of geturl to completely
avoid the issue. This is bad since this version does not allow the event
loop to continue, but good since it works and the server being called is
pretty fast. We can regain CPU utilization in our application since we have
a load balancing proxy in front of our servers anyway.
Do I understand that the recommended idiom for calling geturl inside a .tml
file is this?
set sock $Url(sock)
Httpd_Suspend $sock
set t [http::geturl ...]
Httpd_Resume $sock ?args?
Should I call Httpd_Suspend in my Url_ReadPost fix as well?

Hi - I'm still catching up on email and just found this.
What is your status?
If a domain implementation does "http::geturl" then you'll need to
use "Httpd_Suspend" to clear out file events first. 3.2 adds a
"Httpd_Resume" as well.
