FreeBSD NOTES
DISPLAY OF THREADS
The '-H' option will toggle the display of kernel visible thread con-
texts. At runtime the 'H' key will toggle this mode. The default is
OFF.
Should reveal the "missing" thread(s). This was raised by someone else
last November also examining mysqld. Look for a thread titled "top
incorrectly reporting process time".
