In my current application, I have one page in particular that must be syncronized with an external process, and I am using an flock'ed file to provide a mutex of sorts. The problem is that I cancelled a long running operation (where the file was locked) and it seems that the file does not automatically get closed.
Is there an easy way to ensure that the file will get closed even if the user presses the 'stop' button? I am hoping that there is something simple that I can do rather than a global handler that within I must determine if there is a lockfile open.
Thanks, Tim
