Bug#11748731 - 37248: SOME 'BIG' TESTS FAILING ON 6.0:

Browse Source 
alter_treable-big.test was failing due to the use of RAND() function which is no more 
replication safe.
This has been modified using static values.

Also, 'sleep' has been replaced using 'debug_sync' and the execution time of the 
test has been reduced significantly.

This test is now taken out of the disabled.def file and is being enabled.
