Follow-up Comment #1, bug #26132 (project lwip):

A few questions:

Can you give any information about what sort of performance improvement this
optimization might give?

I notice that your changes remove the "sys_sem_t *sem;" from struct
tcpip_msg.  Is this really unused?

How does the user of the static message know that it is OK for it to re-use
the static message?  Is it implicit that only one of these messages can

Finally, which source version are your changes made against?  They don't seem
to correspond to CVS head.
