LKET will log only the tid for smaller trace data size and faster speed. But
LKET will trace the fork event by default, so the relation between tid,pid,ppid
could be figured out by looking at fork events.
The problem is that, when lket-b2a record the relation of pid/appname, it does
record pid and appname, but when at a later stage lket-b2a retrieve the appname
for a process, it use tid instead of pid to search, and then it will return NULL.
I will fix this in lket-b2a.
