llvm/lldb/source/API/SBProcess.cpp
Greg Clayton 949e82216c <rdar://problem/13009943> 
Added a unique integer identifier to processes. Some systems, like JTAG or other simulators, might always assign the same process ID (pid) to the processes that are being debugged. In order for scripts and the APIs to uniquely identify the processes, there needs to be another ID. Now the SBProcess class has:

uint32_t SBProcess::GetUniqueID();

This integer ID will help to truly uniquely identify a process and help with appropriate caching that can be associated with a SBProcess object.
