Description
if a tshow is happening while another process or other processes/threads are adding to the buffer, the tshow can hang.
I have been able to reproduce this:
window 1: TRACE_SHOW="%H%x %T %N %P %i %C %n %.3L %m" tshow -F | PAGER= tdelta -i
OR while true;do tshow | PAGER= tdelta;done
window 2: while true;do tcntl TRACE 8 hello -l60;sleep 0;done
