rtorrent downloads broken, possibly related to recent mmap work
Running DragonFly v22.214.171.124.gdc43b7-DEVELOPMENT, x86-64
Since upgrading to recent master, rtorrent downloads have been frequently failing with the message "hash check on download completion found bad chunks". I've never that message from rtorrent before. I tried setting machdep.pmap_mmu_optimize=0 and the failures stopped.
