The problem is that in freebsd, attach runs before the scheduler is running. Consequently, code using sleep primitives tends to hang because ticks never advance. The scheduler / threading starts much earlier on linux. -M On Tue, May 10, 2016 at 4:30 PM, Sergey Manucharian wrote: > I was running FreeBSD 11.0-CURRENT r292595 on ThinkPad T430 (i7-3520M, > Intel video 4000).
