You can't have more than 6 timberlake tabs open

This is due to the per-domain open connection limit. (I think it's 6 in both Chrome and Firefox.)

Timberlake keeps an open SSE connection in each tab to get updates. The SSE connection should probably be closed when the tab isn't visible. That would require a resync with the server when the tab is focused again.

[crazyidea] Have a normal HTTP endpoint that lets you ask for updates since $(last time this page saw an update). The response would return all running jobs plus the jobs that have finished since the last update.
