It will. It's purely a question of priorities and time.

For the bug where the stream gets out of sequence, you might want
to start by looking at this fragment of code in nfssvc_nfsd().
/*
* For stream protocols, prepend a Sun RPC
* Record Mark.
*/
if (sotype == SOCK_STREAM) {
M_PREPEND(m, NFSX_UNSIGNED, M_TRYWAIT);
*mtod(m, u_int32_t *) = htonl(0x80000000 | siz);
}
