# Detached threads may not complete deiniitialization by the time shutdown

# thread calls exit. This is unfortunate property of detached threads, which

# between false positives generated by detached threads and real memory leaks
|

# generated by not joined joinable threads. So we hide both cases.

# To avoid enumeration of the whole variety of possible traces we ignore all

# "possibly lost" blocks allocated by pthread_create (and it's callees).
