FWIW, the conflict is not with exec-shield per se, but rather with
exec-shield-randomize, the feature that gets the kernel to randomize memory
mappings. It turns out that the PCH mechanism was built upon the mis-assumption
that memory maps are invariant. I'd rather qualify this as a bug in the PCH
implementation.
