This bug is the result of discussions around Bug 16998


Currently there is no mechanism for the UA to signal that it wants the web
application to stop appending for a while. A UA might want to do this in a
memory constrained environment to help the web application avoid appending "too
far ahead" which might trigger media segment eviction (Section 2.10). 

It could be useful to have a mechanism that notifies the application when
further appends will trigger evictions so the web application could use
remove() (https://www.w3.org/Bugs/Public/show_bug.cgi?id=18709) to control what
time ranges get removed. When the UA determines that enough data has been
removed to allow appending again it can notify the application with an event.
