Two ways.  

1) does the head change ? Afaics it's allways the same, and it's
dataelement is NULL (thats the behaviour I've observed, whether its a
coincidence or not, I don't know). 

2) Store the mutex as first element of list, complicating the use of
foreach.

3) Hope to whatever gods one worships, that I'll only be locking less then
10 lists in a few places, so I can just create a load of mutexes and lock
at free will.

It should be ok. The child process could get a cookie from the parent, use
it in a call like request_completed(cookie,request).

Nope, volunteer work. But it's a students bar, so I don't feel like a
