Could you split this patch into two? One adding lock "support" in the current
performance test code and another one adding the new readwrite tests?

I think " rounded_nb_total_tsx_insertion" and " tbl_multiwriter_test_params"
are too long, and that's why you need to split a long line into two down below.
Could you shorten these names a bit? You can change "multiwriter" to "mw",
and "rounded_nb_total_tsx_insertion" to "total_nb_tsx_inserts".

You can set hash_params.name = "tests" directly.

I think you can have just one label "err" with these two frees.
If the variables haven't been set, they will be NULL and that's allowed.

I see the following error and other errors when compiling with gcc 32 bits.
test/test/test_hash_readwrite.c:281:12: error:
cast from pointer to integer of different size [-Werror=pointer-to-int-cast]

Maybe a comment about this reader_faster would be good.
Also, can we declare this variable and use_html as local and pass them to the functions,
instead of declaring them as global?
