Can GDB handle these? How about Valgrind?

If GDB doesn't need to do single step the region, it should make no difference. Trying to single step the region would restart it indefinitely.

librseq generates a section describing the possible critical sections, so it would be possible to make GDB read it and skip critical sections when single stepping.

Valgring is discussed in the comments of the post, with a link to https://bugs.kde.org/show_bug.cgi?id=405377

In the LWN comments, mjw said that Valgrind just forces an ENOSYS error.
