Dear all, as requested.
Attached is the first of the series of 13 patches which implements a new
shared memory library -lcaf_shmem. All 13 patches should be applied before
attempting to build and test. The change log entries provide explanation as
well as the changes to invoke.texi
Previously identified locking and syncing issues are fixed by patches 11 and 12.
Changes to the configuration and regeneration files are grouped in patch 13.
Jerry sent me a combined version of the patch off-list.
I finally had time to apply the patch and test it.
The patch leads to 170 failures on x86_64-*-freebsd.

Looks like the testsuite is linking against a previously
installed libcaf_shmem.

IMHO, the patch is not ready for commit.
Hi Steve,
I will investigate this soon.
Is there a freeBSD system I can access anywhere?
