This is actually a bug in your NAS. Because if it is online but
shutdown, it must not return ERROR_NOT_READY but just take longer to
return file accesses.
Because ERROR_NOT_READY means that the device is not ready. It doesn't
mean that the device is not ready *yet* and therefore callers don't have
to wait. The windows explorer works around many bugs in device drivers,
one of them being exactly this one (that's also why it sometimes just
'hangs' while retrying to access a device that's not even there anymore).

if you want TSVN to wait here too and work around your buggy NAS server,
you'd have to ask on the svn mailing list for this. Because it's the svn
library that does all the disk access...
