Hi,
With regard to sys_timeout timer and its performance impact,
some while ago I tried to fully replace memp.c implementation with
uC/OS-II's fixed sized memory allocator.
(I have been using lwIP on uC/OS-II.)
This full replacement is fairy effective for performance.

Just now I tried your point...
Oh! performance result is almost same as memp full replacement!
Of course disabling memp_sanity() is better than my workaround from
the perspective of portablility.
Thank you, Luke.
