The pthreads standard defines essentially a set of primitive operations, 
which are then put together to pull off whatever concurency tricks you wish 
to pull.  This means that implementing the "checkpoint" feature you referred 
to isn't necessarily a pthreads issue; only a software design one.  

You didn't said what you mean by "checkpoint".  Without any specific 
details, it might be possible that it only take a single mutex to be able to 
implement your "checkpoints" feature.  Nevertheless, this only depends on 
what your requirements are, and how you designed/will design your software.  
Pthreads is orthogonal to this.


Hope this helps,
