Thanks for the replies.

ptrace will not work - this is not for an strace or debugging tool,
it's for an exceptionless system call implementation, similar to
FlexSC: http://www.eecg.toronto.edu/~livio/papers/flexsc-osdi10.pdf

Obviously, they must have found a way - I'm wondering if they were
using GNU libc or a different library.
