> In {{src/slave/containerizer/mesos/launch.cpp}} a helper function {{signalSafeWriteStatus}} is defined. Its name seems to suggest that this function is safe to call in e.g., signal handlers, and it is used in this file's {{signalHandler}} for exactly that purpose.
> Currently this function is not AS-Safe since it e.g., allocates memory via construction of {{string}} instances, and might destructively modify {{errno}}.
> We should clean up this function to be in fact AS-Safe.
