Thanks!
While on the topic, is there any reason why the backend stays a group leader
for the rest of its lifetime, and should we change that?
Also, while reading ProcKill, I noticed a typo in a comment:
/*
* Detach from any lock group of which we are a member. If the leader
- * exist before all other group members, it's PGPROC will remain allocated
+ * exist before all other group members, its PGPROC will remain allocated
* until the last group process exits; that process must return the
* leader's PGPROC to the appropriate list.
*/
