I think you have your terminology confused.

A servant is just a programming language object. Multiple threads can
call a single servant's methods at the same time. There is no queue
waiting for a servant to become free -- if two calls for a particular
object come in at the same time, methods on the servant are called
concurrently.

I suggest you read the free online book "CORBA explained simply" by
Ciaran McHale, which explains all the terminology well:

Duncan.
