That is a *very* inaccurate description.
It affects only session handler functions which are called
during the request shutdown (write, close). It does not
affect the other four handlers.
Second, it is not a general problem with memory allocations.
Strtok just assumed that it would not be called after request
shutdown. The attached patch should fix that.
