 The difference could perhaps be explained by malloc(3) changes.
 8.x's malloc tries to keep more memory per-thread, which reduces
 contention but increases memory usage.
 
 By the way, your program may behave erratically when it terminates or
 when pthread_create() fails because pthread_cancel() may be called on an
 uninitialized pthread_t, pthread functions are called on detached and
 terminated threads and the signal handler calls functions that are not
 async-signal-safe.
