It does:
open("testfile", O_WRONLY|O_CREAT|O_EXCL|O_LARGEFILE, 0600) = 3
open("/dev/random", O_RDONLY|O_LARGEFILE) = 4
read(4, "<", 1)                         = 1
write(3, "8", 1)                        = 1
...
close(4)                                = 0
close(3)                                = 0

That reading from /dev/random is your problem. You probably have
a system without entropy, or a lot of entropy consumers.
What does:

3609
say on your system?
