Make /events API send headers immediately

Browse source 
Go's net/http API does not send headers until the first call to
ResponseWriter.Write().  Ordinarily, this is fine, because in most
cases, responses are returned immediately.  However, for the events
API, nothing is written until some event is sent, which causes
timeouts and/or hangs in some HTTP client APIs, which wait for headers
before returning from the "make request" call.
