operf sleep 1 sleeping forever

[Breno L. <br...@br...>]

Hi,

I just tested operf on a Power7 machine and it seems to be working fine.
Although when running: operf sleep 1, it sleeps forever, and even ^C
doesn't work. (^Z works and then I can kill the process).

Doing a strace, I found that operf is in a loop as shown above:

mmap(NULL, 1072, PROT_READ, MAP_SHARED, 14, 0) = 0xfffad340000
munmap(0xfffad340000, 1072)             = 0
mmap(NULL, 1072, PROT_READ, MAP_SHARED, 14, 0) = 0xfffad340000
munmap(0xfffad340000, 1072)             = 0
mmap(NULL, 1072, PROT_READ, MAP_SHARED, 14, 0) = 0xfffad340000
munmap(0xfffad340000, 1072)             = 0
mmap(NULL, 1072, PROT_READ, MAP_SHARED, 14, 0) = 0xfffad340000
munmap(0xfffad340000, 1072)             = 0
mmap(NULL, 1072, PROT_READ, MAP_SHARED, 14, 0) = 0xfffad340000
munmap(0xfffad340000, 1072)             = 0
mmap(NULL, 1072, PROT_READ, MAP_SHARED, 14, 0) = 0xfffad340000
munmap(0xfffad340000, 1072)             = 0


I am running perf-events branch, and my last commit is

Thanks
