FYI, this causes segfaults when doing large streaming writes when
running against a sheepdog cluster which:

  a) has relatively fast SSDs


  b) uses buffered I/O.

Unfortunately I can't get a useful backtrace out of gdb.  When running just
this commit I at least get some debugging messages:

qemu-system-x86_64: failed to recv a rsp, Socket operation on non-socket
qemu-system-x86_64: failed to get the header, Socket operation on non-socket

but on least qemu these don't show up either.
