Nope.  That would then not work with multiple instances of konqueror.  Someone
did a smart thing when creating KIOSlavePool and added a static member function
that points to the current instance:

static KIOSlavePool* self();

This is what what KIOJob uses to create io-slaves:

KIOSlave* KIOJob::createSlave( const char *_protocol, int& _error, QString& _error_text )
{
  KIOSlave *s = KIOSlavePool::self()->slave( _protocol );
  ...
}

Hence, the slaves are actually shared across apps even though each app creates
its own KIOJob.
