Usually, happens when I have killed the process the last time.
System: Mac OS X
Do you mean when the last existing process using the enviornment is exiting? If so, that makes sense:
On BSD systems, mdb_env_close() attempts to upgrade the readlock on the lockfile to a writelock. If that succeeds, it deletes its semaphores since this is the last process using them.
But if you mean you killed the process, started another and then close takes a long time, I don't know why.
