Standard task that acts as reader or writer at the head of an ACE_Stream.
A ACE_Message_Block sent to this task (via its put() hook) triggers actions depending on the block type and whether the task is acting as a reader or a writer. If the block is of type ACE_Message_Block::MB_IOCTL, the block's is assumed to contain (beginning at its rd_ptr()) an ACE_IO_Cntl_Msg object and is processed accordingly. This is usually used to set the task's message queue high water and/or low water marks.
When the block is not ACE_Message_Block::MB_IOCTL, processing depends on the ACE_Stream_Head's role in the module:
