# Every thread should be bound to an operating system thread
# (this test is not using the thread_pool)

# Note that this test will fail:
# - on platforms where my_thread_os_id() is not supported,
#   which is not the case on linux
# - if some code in the server does not assign a THREAD_OS_ID
#   to an instrumented thread, in which case this is a bug
#   in the component instrumentation.
