Bug#16859867 INNODB_BUG14529666 FAILS SPORADICALLY IN VALGRIND

Browse source 
i_s_innodb_buffer_page_get_info(): Do not read the buffer block frame
contents of read-fixed blocks, because it may be invalid or
uninitialized. When we are going to decompress or read a block, we
will put it into buf_pool->page_hash and buf_pool->LRU, read-fix the
block and release the mutexes for the duration of the reading or
decompression.
