A packet or streams layer for GENSEC/SASL?

   The same applies to low-level filesystem I/O as well,
with Samba being free to use quite large buffers
and the lower levels optionally shrinking them.

   This is almost the exact opposite of how Samba
works now: unless you specify a large write size,
Samba uses small sized buffers whose size
correspond to what is desirable on the network,
and we hope that read(1) will coalesce them.

   Fortunately this works on Linux, but it's
a giant performance pain on BSD-derived
filesystems (like mine!)
