I get the feeling we have a problem with our subprocess calls and
debugging but its hard to know what to do about it. We can patch each
call site like this but it starts to make we wonder whether we need a
general wrapper, or we're missing something in bitbake or elsewhere to
help with things.
There is this code:
http://git.yoctoproject.org/cgit.cgi/poky/tree/bitbake/lib/bb/utils.py#n378
which is meant to help but it clearly isn't helping/catching all cases.
I think we are going to need to look at a wider/more general solution
or at least have a plan for one.
Cheers,
Richard
