[LTP] [PATCH] syscalls: semop: Increase timeout for semop03

[Jan Stancek <jstancek@redhat.com>]

----- Original Message -----
> Sometimes the timeout happens before the signal is received and it
> causes the test to fail with following error:
> 
>  semop03.c:55: TFAIL: unexpected failure: EAGAIN/EWOULDBLOCK (11)
> 
> Fix this by increasing the timeout to a sufficiently large value.

I see it sporadically on ppc kvm guests too.
