Cygwin: posix timers: allocate timer_tracker on system heap.
Allocating on the cygheap would copy information of the tracker into
the child process. A forked child knows the timer id and could simply
still access the (free'd but still valid) timer_tracker on the heap,
which is dangerous and very certainly doesn't reflect POSIX semantics.
