As far as I am aware, this is not possible without browser modification / through a plugin.

All communication between the renderer and the kernel process in Chrome is done via IPC. Each message from the renderer is serialized and passed to a dedicated I/O thread, which dispatches it to the kernel process. On the receiving end, the kernel process provides a filter interface, which allows Chrome to intercept resource IPC requests (see ResourceMessageFilter) which should be handled by the network stack.

The resource filter runs in the I/O thread in the browser process, intercepts the resource request messages, and forwards them to a ResourceDispatcherHost singleton in the browser process.

The ResourceDispatcherHost allocates to available sockets from the socket pool which...

the browser is able to enforce limits on the number of open sockets
