Just a curious question: is this really necessary for your application
or can you rely on events rather than polling the server every second?

Every request object is disposed after the request is completed, so in
theory there should be no increasing memory consumption. However the
garbage collection mechanism of the browsers do not release memory of
disposed objects right away. So it may lead to a increasing memory
consumption temporarily (before the cycle of the gargabe collector starts).

Rely on events rather than polling the server could be a solution if
this is a scenario for your application.
