things like "rm" getting into the following backtrace:
---------

The machine is alive but a few processes are wedged, including a
vi and a split-include. lord, if you want, please grab the console
and drop into the debugger. you will see the backtrace of split-include
process 29241 is the standard stopped in xlog_grant_log_space:
