indeed without nagle disabled (which is what nodelay does) a pipeline
can be interrupted for a full rtt waiting for an ack, which defeats
the purpose of pipelining. Other parts of FF can just coalesce the
writes internally, but sometimes that is not possible for pipelines
which may not have an opportunity for a pipelined request when the
"runt" packet goes out, but discovers such an opportunity a long time
before the rtt is expired. In other places (such as long posts) we do
a fine job of coalescing already, so this should not result in any
extra packets on the wire, just improved latency.

raise sockettransportservice max sockets to 550 from 50 for linux, os
x, and windows >= xp. This does not change the default http
max-connections config (which remains at 30), but does allow
configurations above 50 to work and will enhance the utility of other
systems that use the sockettransportservice.
win9x provides a small number of sockets (100), so we just leave the
limits unchanged there out of conservatism.
