I forgot to tell you:

Once you have patched MySQL 5 with this patch,
please try to compile the libmysqlclient_r (or libmysqlclient / libmysys)
with gcc with the compiler options:
-O3 -fexpensive-optimizations -funroll-loops

It's possible that without this optimizations, you will not see a big speed
difference.
