The previous approach of storing pointers to messages structures for thread-blocking sendrec operations relied on several assumptions, which if violated could lead to odd cases of memory corruption. With this patch, VFS resets pointers right after use, avoiding that any dangling pointers are accidentally dereferenced later. This approach was already used in some cases, but not all of them.
