If I understand what you're doing, an Ada "protected record" would be
just the ticket here. The queue data is hidden inside and the routines
to insert/remove items are visible, but only one routine is allowed to
execute at a time, so two tasks can't step on each other's feet.
Essentially you let the compiler handle the semaphore for you, making
your life simpler and less subject to mistakes, and the compiler
run-time probably does the job more efficiently.
