Merged with modifications. test_perthreadlock compares the iterator against 0
with a decrementing iterator, so we need to work on long.

The change introduced by commit 0498a00cbc "Fix: sessiond: don't
allocate buffers and files for inactive sessions" adds a
ust_app_global_update() for each application without removing the
pre-existing ust_app_start_trace(), which effectively attempts to start
tracing twice for each application alre
We are experimenting LTTng for tracing multi-threaded program, it works
very well for us. Thank you for having this great tool. But we have some
concerns about the overhead and scalability of the tracing. Could you share
some insight of the following questions?
