Normally Monifu's implementation guarantees that events
are not emitted concurrently, and that the publisher MUST
NOT emit the next event without acknowledgement from the
consumer that it may proceed, however for badly behaved
publishers, this wrapper provides the guarantee that the
downstream Observer given in
subscribe
will not receive concurrent events.
WARNING: if the buffer created by this operator is unbounded, it can blow up the process if the data source is pushing events faster than what the observer can consume, as it introduces an asynchronous boundary that eliminates the back-pressure requirements of the data source. Unbounded is the default overflowStrategy, see OverflowStrategy for options.

There are 3 possibilities:
1. in case skip == count

the call being equivalent to window(count)
2. in case skip < count

number of elements being repeated being count - skip
3. in case skip > count

dropped between windows

Creates a new Observable by applying a function that you supply to each item emitted by the source Observable, where that function returns an Observable, and then merging those resulting Observables and emitting the results of this merger.
This function is the equivalent of observable.map(f).merge

The difference between concat and
merge
is that concat
cares about ordering of emitted
items (e.g. all items emitted by the first observable in
the sequence will come before the elements emitted by the
second observable), whereas merge
doesn't care about that
(elements get emitted as they come). Because of
back-pressure applied to observables, concat
is safe to use in all contexts, whereas
merge requires buffering.
