I'm gussing that a timeout handler (or some functions called from a

sys_sem_wait conditionally calls memp_free which in turn calls
sys_sem_wait....
I did some tests on ecos today and until I made sys_timeout use
statically allocated timeouts (so not calling memp) it crashed when
using lots of timers which fired very quickly.
Did it crash the whole, or just lock the thread which is communicating at that time? I can confirm the latter (timing-dependent) problem. But other threads continue to work. BTW many thanks to you and Leon for keeping up the work!
