Comment(by pacak):
strace shows that compiled version uses select
{{{
open("/etc/passwd", O_RDONLY) = 3
select(4, [3], [], NULL, {134, 217727}) = 1 (in [3], left {134, 217725})
}}}
while ghci version uses epoll
{{{
open("/etc/passwd", O_RDONLY) = 7
epoll_ctl(3, EPOLL_CTL_ADD, 7, {EPOLLIN, {u32=7,
u64=12117878556374073351}}) = -1 EPERM (Operation not permitted)
}}}
