Interprocess should provide filesystem location of shared memory files

[martin.apel@…]

Every now and then we have problems with shared memory files, so our application ceases to work correctly. This is probably not Boost's fault, but a Windows issue. We would like to be able to print the location of the directory, where Boost Interprocess puts its files, so the user can check and possibly clean up the directory. Therefore a method providing this information e.g. as a member function of shared_memory_object would be nice.
