Bug#34891 sp_notembedded.test fails sporadically

Browse Source 
The problem is that since MyISAM's concurrent_insert is on by
default some concurrent SELECT statements might not see changes
made by INSERT statements in other connections, even if the
INSERT statement has returned.

The solution is to disable concurrent_insert so that INSERT
statements returns after the data is actually visible to other
statements.


mysql-test/r/flush_read_lock_kill.result:
  Restore old value of @@global.concurrent_insert
mysql-test/r/kill.result:
  Restore old value of @@global.concurrent_insert
mysql-test/r/sp_notembedded.result:
  Update test case result
mysql-test/t/flush_read_lock_kill.test:
  Restore old value of @@global.concurrent_insert so it
  doesn't affect other tests.
mysql-test/t/kill.test:
  Restore old value of @@global.concurrent_insert so it
  doesn't affect other tests.
mysql-test/t/sp_notembedded.test:
  Disable and restore concurrent_insert value at the end of the
  test case. The test case for Bug 29936 requires that the inserted
  rows need to be visible before a SELECT statement is queued in
  another connection.
  
  Remove sleep at the start of the test, it's not necessary to log
  the result of the processlist command, showing the warnings has
  the same end result.
