2``struct_process'' should also have:
3 * All the symbols it has breakpointed, and, for each of them:
4   - its addr
5   - its return addr, if any
6   - whether the return addr is breakpointed (ie, if the symbol is ``active'')
7   - the original value in the addr, and in the return addr, if appropiate
8   -
9 * The state of the process:
10   - uninitialized
11   - running
12   - within a given syscall
