+I'm having strange issues with my code hanging at shutdown!
+===========================================================
+
+Make sure you explicitly ``.close()`` your connection objects (usually
+``SSHClient``) if you're having any sort of hang/freeze at shutdown time!
+
+Doing so isn't strictly necessary 100% of the time, but it is almost always the
+right solution if you run into the various corner cases that cause race
+conditions, etc.
