Hi, Raymond

Sorry for delay in reply. My understanding is that you are trying to use 
boost::execution_monitor - part of Boost.Test library. Unfortunately this 
component is not thread safe. I've made sure that it reentrant safe. But to 
access it from multiple threads require adding guards for static data and/or 
use of TLS. I did not have time to do this and frankly this is not in my 
immediate to do list. There are some non trivial issues to consider. So you 
only options is single monitor in main thread. And even in this case I am 
not sure if it will work. Especially in regards of exceptions and signals 
handling. You probably will need to go extra mile to get what you want.
