Wow!, thanks for the very thorough review.

I decided to add a bit more info here:

This probe is only available when @code{malloc} is compiled with the
per-thread arenas option enabled (@samp{-DPER_THREAD}); this option is
enabled by default.

Here's how it ended up:

These probes are triggered when the corresponding functions fail to
obtain the requested amount of memory from the arena in use, before they
call @code{arena_get_retry} to select an alternate arena in which to
retry the allocation.

Here's how I rephrased it, so that it ties with the reference to
arena_get_retry in the other _retry probes:

This probe is triggered within @code{arena_get_retry} (the function
called to select the alternate arena in which to retry an allocation
that failed on the first attempt), before the selection takes place.

Thanks.


I'll go through the patchset one more time and then post it, in reply to
*this* message, because that makes more sense than posting it in reply
to the other email I posted today ;-)
