It seems he's talking specifically about the close(2) syscall taking a long time. Someone would have to peek inside the MacOSX kernel source code to answer that question.
Right... Though I can think of one non-kernel possibility:
Previous process wrote something and got killed - maybe while fsyncing the changes. Then rapidly open and closed another mdb env - and close(sync descriptor) waits for the old changes to be synced in order to decide whether to return success or failure.
