Serialize

force an Observable to make serialized calls and to be well-behaved
Serialize

It is possible for an Observable to invoke its observers’ methods asynchronously, perhaps from different threads. This could make such an Observable violate the Observable contract, in that it might try to send an OnCompleted or OnError notification before one of its OnNext notifications, or it might make an OnNext notification from two different threads concurrently. You can force such an Observable to be well-behaved and synchronous by applying the Serialize operator to it.
