FYI we have TST_CHECKPOINT_WAKE() and others, please see
"1.9 Fork() and Parent-child synchronization" in doc/old/C-Test-API.asciidoc
or online
https://github.com/linux-test-project/ltp/blob/master/doc/old/C-Test-API.asciidoc#19-fork-and-parent-child-synchronization

(still not yet converted docs to sphinx)

Also worth to read if you have time (because people would put at least some usleep() instead of plain while(1);

Kind regards,
Petr
