Follow-up Comment #1, bug #46321 (project lwip):
Wow, that's one *long* post!
The best way to fix this would be a call to 'sys_archm_sem_trywait()', but
unfortunately, this function doesn't exist (yet). I'm tempted to introduce it,
though...
Another option would be to wait one milisecond after taking select_cb off the
list (unless we already waited and got signalled)...
