-This manually reverts:
-
-  commit 584a9bceab948590dabd189d234a86e6bf4ec3f4
-  Author: wangqr <wangqr@wangqr.tk>
-  Date:   Fri Sep 1 21:27:24 2017 +0800

-  Find roots when constructing process tree, fix #587
-
-which breaks the process tree (‘t’) view in at least some cases.
-I will investigate further...
