Subject Re: Sharing information between threads and processes.

I implemented something very similar for my module: Dynamic
configuration data is retrieved from a remote server and should be
shared among all worker processes. Fortunately the configuration
changes only sporadically so I implemented it using
serialization/deserialization to/from the shared memory segment. Of
course inter-process locking must be considered - for example using
apr_proc_mutex_* or a spinlock inside the shared memory segment.
