See this mail on lwip-devel:

Summary:
On platform ports where SYS_ARCH_PROTECT() does not prevent scheduling triggered by sys_sem_signal(), the select list can be corrupted.

There was a bug in this region before: bug #31741, fixed with this commit on 2011-01-24: http://git.savannah.gnu.org/cgit/lwip.git/commit/src/api/sockets.c?id=03be8f88feff9ded26d14bf893497764f79fcd2b
