Task deallocation

["Jonas Nygren" <ehsjony@ehs.ericsson.se>]

I have a problem related to freeing tasks, that I can't find a good
solution to. Here follows a short description of my problem.

I am doing a server-task that dynamically allocates sub-tasks to handle
individual requests. I want the sub-tasks to use a terminate alternative
so that they terminate when the server-task is terminated. My problem is
how to reclaim the storage for the sub-tasks. One possible alternative is
to have a linked list of the sub-tasks outside of the-server task and then
scan this list of sub-tasks for terminated tasks and delete them,
recursively
until the list is empty. This code looks a bit on the heavy side and maybe
there is an easier way to reclaim the storage used by these tasks.

Anybody have any good suggestions of a better alternative to the solution I
described above? Any suggestions are welcome.

PS If the sub-task type were defined inside the server-task then it should
   be possible for the Ada RT to automagically free the sub-tasks after the
   the termination of the server-task since they cannot be referenced by 
   any other entity. I have read the Ada RM but I cannot find anything on 
   this topic (except that it is an error to free a non-terminated task). DS
