[racket-dev] overwrite

Dunno whether this helps...

I haven't looked at the pertinent Racket code, but errors like this 
often happen in Unix applications because the mtime of the file is in 
the future relative to the current time clock.  Less commonly, because 
the mtime changed since the file was read by the app or since the app 
last checked.

The most common case can happen because a VC/CM system is updating the 
times (someone mentioned Git, and some other systems do this), because 
it's a network filesystem and the server and workstation clocks aren't 
synced sufficiently, or because NTP or some other mechanism dangerously 
jumped the current time clock in reverse (usually a good NTP daemon will 
slow the clock rather than jump in reverse).
