I was able to answer the above by reading the CVS log entry for
postmaster.c, version 1.199:
Ensure that 'errno' is saved and restored by all signal handlers that
might change it. Experimentation shows that the signal handler call
mechanism does not save/restore errno for you, at least not on Linux
or HPUX, so this is definitely a real risk.
Sorry for the noise.
