* I hope this is usefull.
* If mkdir() is atomic,
* then we do not need to worry about race conditions while trying to make the lockDir,
* unless of course were writing to NFS, for which this function will be useless.
* so thats why i pulled out the usleep(rand()) peice from the last version
*
* Again, its important to tailor some of the parameters to ones indivdual usage
* I set the default $timeLimit to 3/10th's of a second (maximum time allowed to achieve a lock),
* but if your writing some extrememly large files, and/or your server is very slow, you may need to increase it.
* Obviously, the $staleAge of the lock directory will be important to consider as well if the writing operations might take a while.
* My defaults are extrememly general and you're encouraged to set your own
*
* $timeLimit is in microseconds
* $staleAge is in seconds
