Ok well I'm no expert with ada concurrency issues but I would recommend:
1)reading the ada rationale 
2)reading what Cohen has to say in Cohen's Ada book, and 
3)"Concurrency in Ada".   From what I understand this is the better book
for what you want.

The following quote taken from
http://portal.acm.org/citation.cfm?id=211392&dl=ACM&coll=portal#
"Burns and Wellings and their associates were major contributors to the
movement that called for the revision of Ada 83 and its subsequent
upgrade to Ada 95. This book turns their spotlight squarely on the new
language, Ada 95."
4)IMHO You'll find a good way of using multhreaded tasks in the ada web
server sources.  Search for the keyword "task" in their sources and
you'll find what you want.  Be warned you'll need to understand all the
intricacies of "select" statements also.
