Is there any way to disable the session locking in PHP while using the default session handler?
[EDIT:] Or is there at least a way to restart a session after callin
This is a rather old question which I came across while researching session handlers, however the answer is yes it is possible - but not using the default handler (without deep hacking into the filesystem to disable locking).
I have come across the same issue. The important thing to note is that you really must know exactly the consequences of disabling locking!
My solution is part of a larger extension to the session handling mechanism - the Stackable Session Handler which includes storage compatible with the default handler and (optionally) non-blocking session reads and writes.
