ccm stop systematically failed at first time

Hi all,

First of all thank you for this amazing tool.
This is a real pleasure to use it.

CCM has been installed using brew (MacOSX environment).
I am running different clusters (one at a time of course), all based on DSE 4.7.0 and each with a single node with a solr workload (test purpose).
Each time I stop a cluster there is a "Problem stopping node node1" after few minutes waiting.
A ccm status show the node is up.
Then I relaunch ccm stop which works after few seconds.
