Anthony, what is the schedule, if any, for getting a fix for the bug
you refer to? The project I am currently working on, in development
within a win32 environment, but soon to be ported to a VxWorks/PPC
(using pthreads) environment does use interruption facilities. If this
will be a problem for us, let's say not fixed up within the next 6 months,
then I'll have to utilize alternate schemes.
