Returns a new PStore object.

Argument file is the path to the file in which objects are to be stored; if the file exists, it should be one that was written by PStore.

Example

path = 't.store'
store = PStore.new(path)

A PStore object is reentrant. If argument thread_safe is given as true, the object is also thread-safe (at the cost of a small performance penalty):

Example

store = PStore.new(path, true)
