It seems to me now it's cleared only for existing user threads. Aren't we sure new kthreads aren't stopping? > - ltl_atom_set(mon, LTL_NANOSLEEP_CLOCK_MONOTONIC, false); > - ltl_atom_set(mon, LTL_NANOSLEEP_CLOCK_TAI, false); > + ltl_atom_set(mon, LTL_NANOSLEEP_CLOCK_REALTIME, false); > =C2=A0 ltl_atom_set(mon, LTL_NANOSLEEP_TIMER_ABSTIME, false); > =C2=A0 ltl_atom_set(mon, LTL_CLOCK_NANOSLEEP, false); > =C2=A0 ltl_atom_set(mon, LTL_FUTEX_WAIT, false); You missed removing a couple of these in the next branch, the monitor doesn't build.
