src/doc: TODO.ptrace
Log Message:
Update TODO.ptrace
Remove entries:
- remove exect(3) from libc - there is no usecase for it
Interface has been marked obsolete and it's on the queue to be removed for.
- research what happens when a tracee masks signals (including SIGTRAP) and a
breakpoint is triggered
It has been researched and ATF tests added (signal1 .. signal10).
It's currently broken on NetBSD.
Add:
- research support PT_SYSCALL & PT_STEP combined like in Linux
There are circumstances when we want to sstep and catch syscall events.
