xdcr_proxy crashing repeatedly on Windows

1. Install build 676 or higher Windows-64 bit Couchbase Server from http://factory.couchbase.com/job/cs_300_win6408/ .

2. Go through initial setup on console: assign 256 MB memory on first page, otherwise choose defaults. Load the beer sample data.

3. Couchbase Server should start up and the status page should show 0 failed servers. However, the log will show many entries like this:

Port server xdcr_proxy on node 'babysitter_of_ns_1@127.0.0.1' exited with status 1. Restarting. Messages: kernel-poll not supported; "K" parameter ignored
{"Kernel pid terminated",application_controller,"{application_start_failure,ns_ssl_proxy,{{shutdown,{failed_to_start_child,ns_ssl_downstream_proxy_listener,

{listen_failed,eaddrinuse}}},{ns_ssl_proxy,start,[normal,[]]}}}"}

Crash dump was written to: erl_crash.dump
Kernel pid terminated (application_controller) ({application_start_failure,ns_ssl_proxy,{{shutdown,{failed_to_start_child,ns_ssl_downstream_proxy_listener,{listen_failed,eaddrinuse}

}},{ns_ssl_proxy,

On some machines, such as the server currently at 10.17.1.166, running Task Manager will show an erl.exe repeatedly starting and stopping. On my personal VM, I don't experience this, although I do see some of the xdcr_proxy log messages.
