I have also seen the rm -rf problem occasionally on my w7-64 machine,
and I don't think anything from BLODA is installed.
However, I haven't noticed the issue since disabling the search indexer
on my machine. I did this on the hunch that I often delete large
directory trees which aren't very old (e.g. after untar/configure/make
of some source package), and that it wouldn't be a big surprise if
indexing and cygwin's rm don't mix for whatever reason.
