Dear Maintainer,

I'm attaching p23.zst; doing less p23, /\b675\b, then enter,
sleeps less forever while using 100% CPU and with all signals blocked
(incl. SIGINT, SIGKILL, SIGWINCH, SIGHUP, &c.).
It only responds to SIGKILL.

It appears to be reading for a while, but then strace starts being
empty (to the continued tune of 100% CPU).

Best,
наб
