Hmmm. The OP's intent was to:
o Backup all files in the directory
o Then use skulker to delete inactive files.
That fails because backup alters the accessed timestamp.
There may be an inevitable timing window. In the simplest case:
stat( file );
if ( inactive ) unlink( file );
the hazard is that the file may be altered between stat() and unlink().
Can skulker avoid this?
