 Hm, I just noticed that it can time out while setting and clearing
 WDCTL_RST.
 
 Unpatched, it failed while setting WDCTL_RST.
 
 After raising the timeout to 1000 (below mdt_cfis[rhd_control] = WDCTL_RST),
 it started failing while _clearing_ WDCTL_RST.
 
 After raising the other timeout to 1000 (below mdt_cfis[rhd_control] = 0),
 it still failed while clearing WDCTL_RST.
 
 After raising both timeouts to 10000,
 it still failed while clearing WDCTL_RST.  Just much later:
