sounds reasonable.  I wonder what was the experience in the original
watch command about intermediate modifications...

In my case, I might be going to just ignore the mk error messages
for such mk run. :)

the specific example may not be useful but ... you have no idea how many 
times people want this stuff. 

But what about a file that the server can provide that provides info about
metadata changes, i.e. you are reading a
/srv/fsstatus
and as things change you get twstat messages?

i dont think it will work.

let us say i just saved an intermediate version of a.c while doing a
bigger change. then the above script will kick mk process that is neither
needed nor useful. the same is the case when i save a.c but i need to
change 10 other files to reflect the change in all relevant files.
