Applying an operation to a set of threads in RTEMS

[Peter Dufault]

I finally have gotten to reviewing Utkarsh's work in GSOC.  One item that I don't like is that there is a linked list management of the threads that have access to the stack.
I think this access is similar to the file descriptors that are blocked in a select call.  On a given architecture I don't know exactly how many file descriptors I can block, I don't know exactly what the FD_SET macro does, but I have access to multiple file descriptors through the FD_* macros.

Using FD_SET and friends for specifying thread access could be a good model to specify which threads need access to which thread.

However, it won't scale infinitely.  Linked lists won't scale infinitely in real-time either.
