Some typo somewhere... Say, you now have $POST or $_POTS instead of
$_POST...

Reading from the same file on a modern operating system should
require no attention at all; it is handled on the OS level.
Writing... well, read up on flock() and see what the manual has

Thread is a Windows-only concept. On Unix, there are no threads,
only full-blown processes, each with a distinct ID... This is
why file locking would work on Unix, but not on Windows...
