8x shader compilation optimization and watchdog disable

Browse source 
addPlumberPipeline in RenderPipelines.cpp would recompile
a single program 7 more times then necessary.  This was
causing startup times on Mac OS X to trigger the deadlock
watchdog.

Even with this fix, compiling shaders is still too slow,
As a workaround, we disable the  watchdog thread during
rendering pipeline setup.
