Just to confirm, I've got a test case that works like this: 1. fork and install a SIGUSR1 handler 2. tracee does a syscall that gets trapped 3. send SIGUSR1 4. respond from the listener with -ERESTARTSYS 5. see another of the same syscall, even though the tracee still thinks its in the first one 6. respond with something reasonable, the tracee sees this response I think that's the intended behavior. Note that when the listener responds with -ERESTARTSYS and there is no signal pending, the task just dies. That might be reasonable, I'm not sure.
