                                    ^^^^^^^^^^^^^^^^^^^^^^^

This is apparently harmless because, in 'xml2enc_filter_init', the ENC_SKIPTO bit of 'flags' is set to ENC_SKIPTO if 'skipto' is non-NULL.

Failing to do this may lead to a race condition where we send a new request
before the backend really closes the connection (or lost SSL-Alert/FIN make
us think the connection is still alive, until the retransmission).

Also, check c->aborted before apr_socket_shutdown() because it is set earlier,
and there is no point in calling shutdown() before close().

Make systems without unlink() semantic happy by destroying (detaching) the SHM
before removing the base file.
Windows is supposed to have the "delete on last handle closed" semantic but yet
fails here when this handle is owned by the same process (go figure!).

r1702450 changed the behaviour of slotmem_{create,attach}() when given
given an absolute (SHM file )name.
Don't mangle the SHM file name in this case, it's up to the caller to
provide a unique name per call when this matters.
