54 - used new SLF interface to reimplement Coro::Signal gaining
55 some unknown (because I was too lazy), but certain, speedup, and also
56 making signals reliable for the first time.
57 - used new SLF interface and other optimisations to speed up async_pool
58 by a factor of two. It also doesn't rely on perl's exception mechanism
59 to exit anymore. The overhead for terminating an async_pool, coro over
60 a normal async is now very small.
61 - sped up coroutine creation/destruction by 40%.

65 - use new rouse functions to speed up and simplify Coro::BDB.
66 - make "prefer perl native functions" work with threaded perls.
67 - condense Coro::Debug ps output, hint at v and w flags.
68 - (libcoro) lots of minor cleanups and portability improvements.
