Originally reported on Google Code with ID 923

What steps will reproduce the problem?
1. Running enough jobs between remote webdriver and seleium-server will cause the the
following message:

What is the expected output? What do you see instead?

The issue happens *real* quick on Windows XP, and can be improved by  http://support.microsoft.com/kb/196271
But even on a Linux box with over 30000 ephemeral we exhaust this.

The root-cause solution of this issue is to make keep-alives work between remote webdriver
and selenium server. There may also be a case for inspecting socket usage elesewhere
in the application.

Note that this issue *also* happens between the client and firefox, if run locally
or remotely. But this is slighlty less serious as it can be "mostly" solved by increasing
the number of ephemeral ports locally. But a single bamboo server can be used to drive
a truckload of clients, in which case 60000 sockets may be too little.

Fixed in r10082, set the re-use option on the socket. Fixing keepalives would still
be nice for performance, but this fix should have impact for both client->firefox and
buildserver->selenium-server socket usage

This still appears to be a problem for me on Windows Windows
Server 2008 using 1.0b version of WebDriver. I am unclear if this fix is in 1.0b.
