Guys,

This patch fixes a problem caused by a difference in the behaviour of
mmap on HP-UX which was mentioned a few days back as affecting
eval_12.pir:

mmap does not seem to allow multiple calls with MAP_SHARED on the same
file, and will return ENOMEM after the first call. What this change
does is fallback to attempting a private mmap if the preferred shared
one fails.

Regards,

Nick

I think we should better protect against multiple loadings (mmapings)
of the same file. HP-UX seems to be good at detecting this ;-)
