Following up - does anyone have any ideas on this?

I also, filed a bug:

<SNIP> (see all the hardware details at the bug, in an attempt to not spam

"Never write it in C if you can do it in 'awk';
 Never do it in 'awk' if 'sed' can handle it;
 Never use 'sed' when 'tr' can do the job;
 Never invoke 'tr' when 'cat' is sufficient;
 Avoid using 'cat' whenever possible" -- Taylor's Laws of Programming
