Even faster: what's coming across that wire should be a constant (is?),
variable is only delivery/consumption jitter.  If there's really really
a pipe problem lurking, you should also be able to trigger by saving
the data once, and just catting it, letting interrupts etc provide
jitter.  Which stdout is left of '|' in a script shouldn't matter one
whit to the interpreter/kernel conversation, they're all the same.

That said, if I had a reproducer I was confident pointed to the kernel,
I'd try to bisect.. boring as hell, but highly effective.
