[lldb-dev] [PATCH] Avoid leaking file descriptors.

[Piotr Rak]

My feeling was when I looked at it bit, that it is related to some thing
I've seen about symbols earlier. In some cases we got some
strange symbol (address pointing to location where it fails set
breakpoint), but have not nailed it down to anything specific, and did not
have time to dig deeper yet. It looks like edge case, rather like something
totally broken though.

And indeed, this one doesn't look very nice.
