Issues with ptrace_check_attach(),
- it does utrace_control(UTRACE_STOP).
This is wrong, ptrace_check_attach() must be "passive",
while utrace_control(UTRACE_STOP) can actualy stop the
tracee.
- even if it doesn't, this is wrong when we have multiple
tracers. ptrace_check_attach() should not succeed if the
tracee was stopped by another engine.
- it ignores "int kill".
Can we ignore these problems in V1 ? Or should we fix something?
