Yeah, I tested it. It might not be locks but its still the same promise.
I consider this is correct behavior. You have to have something to
differentiate promises from each-other. You are doing that with your use
of classes. It could also be done with the use of handle
Here is a longer contrived example. You can see that there are 9
promises but only 7 are actually different. The 8th is a duplicate of
the 5th, and the 9th is a duplicate of the third. But as long as
something is different then each promise is recognized as an individual
promise.
If you look in the verbose output you can see two messages where
"This promise has already been verified". Maybe it would be helpful if
it showed the line number there or a promise handle by what was already
verified.
Does this make more sense?

"main",

# Duplicate of 5th
"/bin/true";
# Duplicate of third
