Small test case. Compile with MSVC debug and run

The routine getElapsedWallTime() in Process.cpp allocates dynamic memory on
line 36 (trunk). Since the memory is assigned to static in local scope the
block is leaked when program exists.

Note: When linking LLVM/CLANG and boost unit test infrastructure using MSVC
this leak is shown upon process exist. Boost enable the MSVC runtime dynamic
memory debugging very early and traps all allocations.
