I have three threads. Two of them are independent and they can run in
parallel. The third thread depends on results returned by the first and
second threads.

Right now I use a condition variable to wait in the third thread until
the first and second threads are finished (by checking two boolean
variables that are set to true once the first and second threads
finish).

In a later scenario I may need to query those threads anytime to suspend
or terminate them (the threads will run trajectory computations for a
helicopter: takeoff, approach and cross-country flight).

I was wondering if there is a boost-way to obtain state informations
about a thread.
