SVN rev 212873 on 2010-09-19 19:42:04Z by alc
Allow a POSIX shared memory object that is opened for read but not for
write to nonetheless be mapped PROT_WRITE and MAP_PRIVATE, i.e.,
copy-on-write.
(This is a regression in the new implementation of POSIX shared memory
objects that is used by HEAD and RELENG_8. This bug does not exist in
RELENG_7's user-level, file-based implementation.)
