IMHO, this level of abstraction goes too far. It may be that I am not 
familiar with process groups, and I find the implementation of 
is_foreground_fd() in progress.c close to where it's used quite 
educating and enlightening. Hiding a similar implementation miles away 
in cache.h and/or compat/ would not pay off for me.
