Yes.

Maybe has some performance penalty. But if there is a performance
decrease, I do not think that it is huge.
Normally creating a class is not more costly than creating a C struct
and initialize it. The AsyncCall classes are very simple classes.

Moreover, I believe with current design you are loosing more in
performance, trying to prevent problems adding extra code for tests or
workarounds.
