Just for the record, I dont' use FastCGI and have seen Zope
die under the same circumstances; ie. by disconnecting the 
browser mid-download of a (usually long) page. Fortunately, 
that 'client' has been me via the administration screens, 
but it does seem like a rather trivial DoS. 
But it seems that this only happens with certain types of
pages - I'm not sure which.

Unfortunately, I can't remember if this was when we were using 
PCGI or Proxy-Pass, but it was definitely one of the two.

Hearing that others are now experiencing the same gives me
hope: this could explain the crashes that we've been plagued
with for months (though I fear any solution will come too late
to prevent our switch to an alternative platform).

ps. Weird thing : the most stable Zope installation I have
    is on NT. It never, ever crashes, despite being the 
    development machine (I wouldn't say that load is causing
    my production server to die b/c it happens under low load
    too).
