mysqld_safe start does not give back prompt on succes when running with --user option

I recently installed an instance of Maria DB 10.0.21 on my laptop from a tarball (with glibc) and went through my installation fine but when trying to start the daemon with --user=mariadb (as this is the user I'm using for the db server) the prompt keeps adding dots to the "Starting MySQL" message without ever stopping even though in the log file

.err I can see that it successfully started and mysqld_safe status returns a "running" message.

I haven't tried to do it with the standard mysql user so I don't know if it happens with the standard user, I guess not because I did not see another bug report for a similar case in JIRA.

Note : I was previously using MySQL server 5.6 with the standard user.
