0001 konq_run / krun should determine the mimetype by actually
0002 getting the contents of the URL. It should then put the slave
0003 on hold and tell the job-scheduler which request the
0004 slave is currently handling.
0005
0006 Now krun/konq_run should determine which client should process the
0007 result of the request.
0008
0009 * When the client belongs to the same process, no action needs to be
0010 taken. When a new job is created for the request which is on hold the
0011 existing slave will be re-used and the request resumed.
0012
0013 * When the client is an external process, the on-hold-slave should be
0014 removed from the job-scheduler and should connect itself with
0015 klauncher. This is hard because it must ensure that the external
0016 program does not request the slave before it has been transferred to
0017 klauncher.
0018
0019 * When a slave is on hold but not used for a certain period of time,
0020 or, when another slave is put on hold, the slave should be killed.

0022 =====
0023
0024 The slave must emit "mimetype" during a GET before the first data is send.
0025
0026 It may wait with sending "mimetype" until it has enough data to
0027 determine the MIME type, but it should not pass any data along before it has
0028 sent "mimetype".
