Suppose that a suspend function
foobar() is called. Inside that function,
withContext(NonCancellable) is used. And,
foobar() itself is also called inside a
In such a case, is the inner
withContext(NonCancellable) block (= the one inside
foobar()) a no-op? Or do such constructs incur a small performance hit?
And if we for example replace
NonCancellable with a certain dispatcher (in both the outer and the inner
withContext block), is the behavior different? Is a duplicate inner
withContext block a no-op only with some context types, with none, or with all…?
