Hi,

Let us consider following execution sequence:

1. "io_service" destructor calls "io_service::service::shutdown_service";

2. documentation of "io_service::service::shutdown_service" says that it
should destroy all user defined handler objects.

Is it true that user defined handler objects may access to (e.g. post a
handler) that "io_service" being destroyed and therefore has not exist
already?

Could You please also clarify me what does "user defined handler object"
really mean?

Thanks,
Andrew.
