This assumes that the request is used with backlog. For non-backlog
requests this would result in a memory leak as EBUSY in that case is
a fatal error.
So this API can't be used without backlog.
We could introduce a flag to indicate whether we want backlog or not,
or maybe we should change our API so that in the non-backlog case we
return something other than EBUSY.
Opinions?
Thanks,
