These modifications were made to synchronize some of 
the initialization methods on an object lock and prevent 
multiple threads from accessing data simultaneously.  
Some problems were found that some of the member 
variables were being simultaneously read and written by 
different threads, so some extra precautions were added 
in to the code to verify that access to these variables is 
thread safe.
