* NAME
* safe_write_file - Write a file out atomically
* DESCRIPTION
* safe_write_file() Writes a file out atomically by first writing to a
* temporary file of the same name but ending with the pid of the current
* process, them renaming the temporary file over the original.
* INPUTS
* $filename - string containing the filename of the file to write
* $content - string containing the file content to write to file
* $force_binary - boolean denoting whether we should force binary
* mode writing.
* RESULT
* boolean - true if successful, false if not
