For 3.7.0, I work or can work or provide help on:

* (of course :) 214909  gdbserver integration (and the delta leak to follow)
   I have just uploaded a new version (upgraded to last SVN + retested on many platforms)

* 250101 (quadratic memory usage for some realloc patterns of big blocks)
   Some days ago, uploaded a new patch version updated to a recent SVN
     Once this is integrated, if I have time, I might work on
     250065 Handling large allocations
     (I find this one important, as doing big alloc/free decreases significantly the
      probability to find dangling references).

* 267925 laog data structure quadratic for a single sequence of lock 
   I have a working patch doing garbage collection of the laog data structure.
    Good results obtained (i.e. helgrind now works on a big appl. at my work,
    doing many locks. And it found some wrong lock ordering :).
    However, I believe a simpler data structure might be possible, so will investigate
    further before posting the patch.

I can't really help but a fix or integration of a patch would be nice for the following:

219156 Valgrind does not handle custom allocation functions
  A patch is attached to this, to support tcmalloc. At work, we will very probably switch
  to tcmalloc, so ...

271438 sse4-64.c does not compile on at least 2 distrib
  This is quite annoying when trying to run the tests.
