Thank you, Daniel, for taking the time to analyze my traces
and to explain the problem so perfect, that even non-net-developers,
like I, can understand it. (-;)

The OS is Darwin 8.8 / Mac OS X 10.4.8, a 4.4BSD descendant and
the relevant source may be in netinet/tcp_output.c, found here

Good news is that your diagnosis could bring us forward to resolve
a long running painful bug filed against  Mail.app, the Apple email

If you agree, I would like to add your diagnosis to my open bug
report and
cross-post the  mail on the Darwin Developers list, before filing a new
bug against Darwin.
