[Boost-users] asio problem

hi,

sorry for the vague question, but i'm not entirely sure what the problem here
is...

i have a class hierarchy (has-a relationship) like this:

  fcgi_server_connection
  +-fcgi_application
    +-fcgi_cgi

fcgi_server_connection has a tcp::socket 'server_socket'.  fcgi_cgi has
another tcp::socket, 'child_socket'.  the program asynchronously reads
messages from server_socket then writes them to child_socket, and reads messages
from child_socket then writes them to server_socket.  (there is some
intermediate processing, but i don't think it affects the problem.)

the problem  occurs when deleting these connections.  firstly,
fcgi_server_connection is deleted.  this deletes fcgi_application, which
deletes fcgi_cgi.  the sockets are member objects, so they are deleted as part
of this.

the actual problem is this: sometimes, after a socket is deleted, instead of
oustanding read/write operations returning with asio::error::operation_aborted,
they return with no error (error==0), but with socket.native() equal to -1.

my understanding is that once the socket is deleted, all outstanding operations
should be cancelled and operation_aborted should be returned.

is this right?  if so, what might cause the behaviour i'm seeing?  and if not,
what am i missing?

thanks,
        - river.
