Experimental Physics and Industrial Control System

Hi,

I have pushed my spinlocks branch onto Launchpad at
https://code.launchpad.net/~epics-core/epics-base/spinlocks

This has two variants of posix implementations (pthread_spin if
available, else pthread_mutex), one for vxWorks/single CPU (intLock),
and a default implementation (epicsMutex).
I added test code (based on the tests for epicsMutex), and tested both
posix variants and the default implementation on my Linux box.

On this machine, I found the posix spinlock implementation working about
twice as fast as the posix mutex.

Please test and verify on other platforms
(RTEMS/vxWorks/Windows/Solaris/OSX) if you have a chance.

Thanks a lot!
~Ralph
