Hi Mirko --

It's quite complex to use the externally distributed libdispatch with Mac OS X 
versions that include GCD support, as the integrated version conflicts with 
the externally linked version.  I'm not sure what the best solution to this 
problem is, but it might involve symbol munging such that the external version 
offers similarly named symbols that do not conflict with the libSystem 
symbols.  Possibly renaming all symbols when linking the library to 
libdispatch_ instead of dispatch_, allowing applications to select which 
implementation they're using?

Just hand-waving, I'm afraid, but it would be useful if someone found a clean 
solution here that didn't involve rebuilding libSystem.
