Subject2.4.1pre8 slowdown on dbench tests

Hi,

On my dbench runs I've noted a slowdown between pre4 and pre8 with 48
threads. (128MB, 2 CPU's machine)

pre4:
Throughput 7.05841 MB/sec (NB=8.82301 MB/sec 70.5841 MBit/sec)
70.94user 232.54system 15:17.39elapsed 33%CPU (0avgtext+0avgdata
0maxresident)k 0inputs+0outputs (1277major+1586minor)pagefaults 0swaps

pre8:
Throughput 6.11383 MB/sec (NB=7.64229 MB/sec 61.1383 MBit/sec)
70.67user 184.18system 17:38.98elapsed 24%CPU (0avgtext+0avgdata
0maxresident)k 0inputs+0outputs (1277major+1586minor)pagefaults 0swaps


There have been no VM changes between pre4 and pre8.

Jens, can be the -blk patch the reason for the slowdown I'm seeing?
