I cannot reproduce this on stable/10:
pooma% stty tostop
pooma% ./pr203765&
[1] 62024
pooma%
[1] + 62024 suspended (tty output) ./pr203765
pooma% fg
[1] + 62024 continued ./pr203765
Thread 1 message Thread 1
Thread 2 message Thread 2
pooma% jobs
pooma%
Same when I tried the same sequence jailed.
First question, can you reproduce the behavior on the host ? If no, compare
the libc and libthr on the host and in the jail.
Second question, if the behavior is reproducable on host, try, at least
temporary, installing stable/10 kernel without touching the userland, and see
if the issue is still there
