sure - it's racy.
I don't think sftp should attempt to do magic to work around filesystem
corner cases, especially when rm(1) doesn't.
OTOH we should offer users the ability to truncate a file themselves if
we don't already.
Does "put /dev/null file-to-delete" work to truncate? AFAIK it should
because we open(.., O_TRUNC, ..)
