hi!

lsftp, the sftp client of the lsh-suite seems to leak memory while
doing a (recursive) "put" on directories. recursive "get" and "put" of
single files work just fine. here's the trace:

doesn't look good, does it? it still copies some of the of files of
selected directories, btw. the ssh server is lshd on a machine also
running wheeze.
