I doubt the changes from 2.7.2 -> 2.7.3 could've caused crashes, I
suspect something else in the stack (eglibc?) broke between them.

Does 2.7.4 work?

Hopefully the Debian SPARC maintainers can help narrow this down.  I
suspect other Ruby software has similar failures, too.  It's definitely
low priority for me (and probably you :)).

Somebody who cares about the platform should investigate.

If it makes your life easier, I wouldn't mind at all if you mark kgio as
unsupported on rare Debian platforms.  x86-64/x86 are my main
priorities.
