Thank you for your fix, Serhiy.  It makes the class behave consistently.
 However, busy processes are going to concurrently build multiple
temporary entitydefs objects before one of them wins, which is probably
worse than the greedy starting that such lazy initialization tries to
avoid in the first place.  Doesn't that design deserve a comment in the
code, at least?
