we can copy using a spawned rsync process.

that converts the uids & gids in a loop.

"testtmp/" name prefix (i.e. using a subdir).  This allows me to create
a testtmp as a symlink to a different file system to assist with testing
ACLs and xattrs.

is forced, which makes some testing idioms easier.

working because it is not yet using --inc-recursion.

relative source path.

  rsync -av lib/*.c /var/tmp/lib

Let's restore the full test suite and find out.

of incremental recursion.  If this still avoids the hanging, I
will need to try to track down how inc_recurse can deadlock.

incremental recursive mode (and an option to negate that).

protocol 30.

so let's try some remote-diagnostics (let's try protocol 29 first).

take fewer protocol bytes and use one less bit in the XMIT_* flags.

device, we need to allocate 2 extra option slots for the device
numbers.

a function & struct that is not available in the rsync code.

compile farm at the moment.

didn't explicitly ask for ACLs.

that makes it incompatible with all prior versions.  A patch will be
provided to allow talking with older (patched) rsync versions.

time-based to count-based (keeping the newest 10 items).
