I agree wholeheartedly. Perhaps there should be a mechanism for the 
client to provide a function for boost to call on assertion failures, 
with a prototype something like:

typedef bool (*assertion_failure_fcn)(void* arg, const char* file, 
unsigned line, const char* message);

The function would return true if the desired behavior is to continue 
past the assertion, false if the system should abort.

The registration function might have prototype

void set_assertion_failure_fcn(assertion_failure_fcn f, void* arg);
