Hi all,

I'm trying to use the shared memory functionality of the boost 
interprocess library for implementing a client and a server like 
process, where the server calculates something for the client. I use 
condition variables for the process synchronization. The implementation 
works initially, but I am getting deadlocks, now.

I appended a pseudo code example of my implementation. One instance of 
the SharedData class is hold in shared memory. On deadlock, both 
processes are hanging in the wait() functions. What am I doing wrong?

Many thanks for any hint. Regards

Kai
