The same applies to restarted requests until Squid discovers that the
provious request is truly aborted, which in 1.2beta does not happen
untill data is flowing.

Yes. Stalled transfers should be more obvious when using Squid than
other proxies. The difference is that Squid reuses ongoing requests for
the same object, while most other (including Netscape) always starts a
new request for the object.
