- * QUIC Thread Assisted Functionality
- * ==================================
- *
- * Where OS threading support is available, QUIC can optionally support a thread
- * assisted mode of operation. The purpose of this mode of operation is to
- * ensure that assorted timeout events which QUIC expects to be handled in a
- * timely manner can be handled without the application needing to ensure that
- * SSL_tick() is called  on  time. This is not needed if the application always
- * has a call blocking to SSL_read() or SSL_write() (or another I/O function) on
- * a QUIC SSL object, but if the application goes for long periods of time
- * without making any such call to a QUIC SSL object, libssl cannot ordinarily
- * guarantee that QUIC timeout events will be serviced in a timely fashion.
- * Thread assisted  mode is therefore of use to applications which do not always
- * have an ongoing call to an I/O function on a QUIC SSL object but also do not
- * want to have to arrange periodic ticking.
- *
- * A consequence of this is that the intrusiveness of thread assisted mode upon
- * the general architecture of our QUIC engine is actually fairly limited and
- * amounts to an automatic ticking of the QUIC engine when timeouts expire,
- * synchronised correctly with an application's own threads using locking.
