It is a two edged sword. There have been bugs where the we call the 
global function instead of a local one, and local instead of a global. 
Used to be quite complex/confusing with the hpi interface - too many 
open/close/read/write methods.

Personally I find it totally unnecessary and distracting on things like 
pthreads library calls. We should never define our own methods with the 
same names as those.
