Yes, it's quite possible that it's a time-out. Neon (the client-side
http library) is probably timing out after 90 secs...

Ay-ya-yay! 40,000 entries in one directory!!

I believe that for a DAV-based checkout, a PROPFIND "get all props"
request is sent on the directory. The server then sends a big list of
entries as an xml body-response. The client parses the xml, and
starts doing GETs and PROPFINDs on each individual file.

I *thought* that the server would be streaming the humongous
40,000-entry response, so client-side parsing can start right
away... we have a brigade for that now, or something. Maybe gstein
can comment?

Regardless, repeat the expermiment while using Ethereal to capture the
data. When the client dies, take a look at the HTTP dialogue and see
how much data was sent.
