IE/NS have the same problem, but you don't see it because they simply try to
connect again if the first connection attempt fails. You can do the same thing
with REBOL.
There is not much else you can do. Usually this is caused by incorrectly
implemented workarounds for the SYN flood problem at the server, e.g. the
SYN cookie
scheme in some Linux versions. Under heavy load and in congested
networks this can cause TCP protocol violations in the 3-way TCP handshake
and can lead to timeouts at the client.
