why don't you use the new db_virtual module with a failover 
configuration: define a new virtual db connection that has behind a 
primary mysql conn and a secondary (failover only) flatstore/dbtext 
conn. So, if DB fails, you will start writing to a local file.

To be honest I do not advices using thread in current opensips as you 
have multiple processes already. And the combination of threads and 
processes may be unpredictable.
Anyhow, regarding your question - the global vars are init only at 
startup time - but note that "global" is as visibility in the code and 
not global "in all processes". Each process will have its own copy of 
the var.

Bogdan
