Yes and no. Java's object creation times (using Sun's JDK on a SPARC)
are _huge_ compared with other operations, and _way_ bigger than object
creation in for example Smalltalk, which also has quasi-parallel OOP.
One of the Erlang people pointed out to me that existing Java systems
have a single shared heap instead of a per-thread heap, so that object
creation has to involve locking, but that can't be the whole story.
