Jie Yu commented on MESOS-1023:
-------------------------------
Interesting! That mean if we call "while(1);" in a destructor of those
variables, exit will be blocked... I did a simple test, and it's true!!!
> Replace all static/global variables with non-POD type
> -----------------------------------------------------

> Project: Mesos
> Issue Type: Bug
> Components: general
> Reporter: Dominic Hamon

> See
> http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml#Static_and_Global_Variables
> for the background.
> Real bugs have been seen. For example, in process::ID::generate we have a
> map<string, int> that can be accessed within the function after exit has been
> called. Ie, we can try to access the map after it's been destroyed, but
> before exit has completed.
