I completely agree with you; It's good to see there is interest in the
lwIP stack from developers that are concerned abouts its correctness.
The SYS_LIGHTWEIGHT_PROT protection was introduced by one of the
developers using the stack to protect *ONLY* between interrupt context
and single-thread user-space context if I am not mistaken.
I am all for removing it, because the locking solution does not scale
across different platforms.

Leon.
