Inter-process locking may be broken on NetBSD under some conditions.
(This didn't get worse since previous package.)
Field tests (benchmarks/skampi) don't reveal that the relevant
code path is invoked.
Major Changes in OpenPA v1.0.4
* native ARM (v7 and higher) support
* numerous memory barrier placement improvements in queue and test code
* x86 memory barrier improvements, including for Intel MIC
* numerous build system improvements
Major Changes in OpenPA v1.0.3
* Libtool shared library support for OPA, avoiding shared/static mixed
linking problems on some platforms.
* The build system should now work more portably with broken/exotic shells.
* pkg-config support
* Emulated atomics can now be detected by the presence of an OPA_EXPLICIT_EMULATION
#define in opa_config.h.
* PPC types are now correctly aligned to 8 bytes instead of 16 bytes.
* many more tests for "make check", fixed missing memory barriers in one test
