Print Jobs
When sending print jobs back to back .. say 5 times or so .. sometimes a
character or two get droped .. causing the printout to be some what
garbled. This happens from NT as well ... heh .. which is really fun when
they're printing postscript .. cause when the 1st character or so is
droped from a postscript print job .. it's postscript commands are printed
out as ascii.
Is anyone else out

[libnbd PATCH v3 09/29] lib/utils: introduce async-signal-safe execvpe()
...t define 'set -s', and in fact, bash treats 'set -s' and
'set +s' as errors. But sh itself DOES have a -s option (mandated by
POSIX), and POSIX also mandates that shells must accept options with a
leading '+'. So in practice, what happens is that both bash and dash
_happen_ to parse and silently ignore '+s' as an unknown option when
passed as a command line argument under the invocation name 'sh',
since they already have to do similar command-line parsing for 'sh -a'
vs. 'sh +a'.

[RFC PATCH] protocol: Add NBD_CMD_FLAG_FAST_ZERO
While it may be counterintuitive at first, the introduction of
NBD_CMD_WRITE_ZEROES and NBD_CMD_BLOCK_STATUS has caused a performance
regression in qemu [1], when copying a sparse file. When the
destination file must contain the same contents as the source, but it
is not known in advance whether the destination started life with all
zero content, then there are cases where it is faster to request
