PSCP and PSFTP on Windows can hang on exit in various failure situations.
Many of these involve the -batch option, which is embarrassing.
- User aborts at host key verification (or -batch is specified,
which has the same effect).
- -batch is specified and no non-interactive authentication
method is successful.
Interestingly, Plink does not appear to hang in similar situations (and
nor does PuTTY proper).
PSCP/PSFTP do not hang in all failure situations -- for instance,
they appear not to hang when interactive password authentication fails.
Looking at when this crept in, it might be another side-effect of the
introduction of the winhandl.c mechanism.
