This project is an attempt to implement the checkpoint-restore functionality
for processes and containers without driving too much code into the kernel tree,
but putting there "various oddball helper code" instead.

Is CRIU able to checkpoint a process tree where one or more processes
are traced using ptrace()?

No it's not (currently).

crtools seem to use ptrace() to execute parasite system calls.
AFAIK this will only work if the target process is currently not
ptraced() by another process.

Yup, exactly.

Thanks,
Pavel
