No worries. I've been sidetracked into other projects, too.

OK. I'll try to work on that (unless you have more time now, I've
been sidetracked too :x)
While we're on ABI/API changes, there's also several other changes
I would like:
* Remove the pthread_mutex_t requirement in the wfcqueue and lfstack
I suppose we could implement limited new classes and layer the
complete old ones on top to preserve ABI/API compatibility.
* cmpxchg_double (cmpxchg16b on x86-64) so lfstack can use
a lock-free stack for single pop operations. I'm currently using
ck_stack from ConcurrencyKit, but generally prefer using the
URCU APIs and it would be great if lfstack could support this
on some arches.
Do you have any timeline for a 0.9 release?
