   4 Subject: selftests/tls: add test for sleeping even though there is data

   8 [ Upstream commit 043556d0917a1a5ea58795fe1656a2bce06d2649 ]
   9
  10 Add a test which sends 15 bytes of data, and then tries
  11 to read 10 byes twice.  Previously the second read would
  12 sleep indifinitely, since the record was already decrypted
  13 and there is only 5 bytes left, not full 10.
