This looks fine, but I have a vague worry about breaking the build on
old C libraries that don't define the st_mtim field. Does anyone know
when this entered the standard?
It's not in *any* accepted standard other than glibc.
http://pubs.opengroup.org/onlinepubs/009695399/basedefs/sys/stat.h.html
Please #define accordingly, for OS's other than Linux w glibc.
Or tackle the problem a different way:
Store st_mtime, add a 2 second timeout to the event loop to look again
at the file
If the st_mtime is the same as stored read it, otherwise timeout for
another 2 seconds.
Once read, poll at normal intervals (whatever they are).
Or go the proper way and use inotify for linux and kevent for BSD and
get file change notifications rather than the inefficient polling.
