Performances tests:

I tried to run the staff_benchmark on this patch, (with memcached) and so no
noticeable performance improvement
Bug 8089

With patch and with cache
Benchmarking with 20 occurences of each operation and 30 concurrent sessions

checked with  perl -MCache::Memcached -MData::Dumper=Dumper -le 'print
Dumper(Cache::Memcached->new(servers => ["localhost:11211"])->stats);'
that memcache was running & accessed:
'get_hits' => '1284',
'cmd_get' => '1302',

Could not find any problem, so ... patch pushed

(but I still think we [c|sh]ould store all sysprefs in a single cache entry)
