  b) when collecting initial hot entries have to remove
  from queue if somehow got there.
  
  b) is easy to get with large buffer cache (256M).
  a) or b) is probably cause of bug#20612.

storage/ndb/src/kernel/blocks/pgman.cpp:
  Under heavy insert PGMAN can run out of page entries
  even when set to 100 times page cache entries.
  
  In this use pattern the extra entries remain idle
  on LIRS stack.  Only ONSTACK is set.  There is not
  enough activity to free them the normal way.
  
  A study of PGMAN / DBTUP behaviour is needed.
  
  This patch adds new sublist SL_IDLE.  When page entry
  pool is empty, an idle entry is released from SL_IDLE
  front if there is any.  Otherwise, we still crash.
  
  The factor above is set from 100 to 10 (still high).
