Or...

Perhaps it's time for a SysDep or Environment module, which can be
queried to determine the facilities available on a particular platform


  SysDep::signalList  -> Array

  SysDep::can(:popen) -> true,  false,  or nil
                                  \         \___ not available
                                   \
                                    \___________ partly available

  SysDep::MAX_OPEN_FILES


and so on....
