  No.  The module is NOT having "a new instance created".

  A module "instance" is defined by a module configuration.  One
configuration: one instance.

  The "instance" data is *constant*.  The module gets called multiple
times simultaneously from multiple threads when multiple requests are
received.

  Why?

  Is that connection changing the way the module behaves?

  If you need to store data that is associated with a particulare
*request*, and is valid only for the lifetime of a request, see
request_data_add(), and request_data_get().
