Hello,
I applied the patch to current HEAD. There was one failure (attached), 
freelist.rej
<http://postgresql.1045698.n5.nabble.com/file/n5804200/freelist.rej>  

Compiled the provided pgbench.c and added  following in .conf 
shared_buffers = 128MB            # min 128kB
Shared_buffers=64MB
Priority_buffers=128MB

I was planning to performance test later hence different values.

But while executing pgbench the following assertion occurs

LOG:  database system is ready to accept connections
LOG:  autovacuum launcher started
TRAP: FailedAssertion("!(strategy_delta >= 0)", File: "bufmgr.c", Line:
1435)
LOG:  background writer process (PID 10274) was terminated by signal 6:
Aborted
LOG:  terminating any other active server processes
WARNING:  terminating connection because of crash of another server process
DETAIL:  The postmaster has commanded this server process to roll back the
current transaction and exit, because another server process exited
abnormally and possibly corrupted shared memory.

Is there a way to avoid it? Am i making some mistake?
regards
Sameer
