Thanks for the comments. Please see PS8. I talked to Casey about writing tests 
and he recommended to write a custom_cluster test.

File be/src/util/minidump.cc:

Done


Line 69:   string pattern = FLAGS_minidump_path + "/" +

Yes, changed it.


Line 79:       // To prevent us from messing with a file that is currently

The cases I had in mind at the time were multiple daemons writing to the same 
folder. After moving each into their own folder and disabling periodic cleanups 
it only leaves test setups where multiple impalads run on a single machine 
where one could startup while another one crashes. However that seems very 
unlikely, so I removed that part of the code.
