It looks like SYS_dup2 is missing for this:

/lib64/libc.so.6 0xf79ae -- open("newfile", O_WRONLY | O_CREAT | O_NOCTTY | O_NONBLOCK, 0666) = 6
/lib64/libc.so.6 0xf82e5 -- dup2(6, 0) = ?
/lib64/libc.so.6 0xf82e5 -- dup2(6, 0) = -95

It is, dunno why I started looking at -2 returns.

Actually "touch" failed because of utimensat was not implemented. dup2 failure didn't matter.

With current master "touch" crashes because of libpmemfile bug - utimensat is in filter_table, but not handled in dispatch_syscall.

I'm working on it (#175).

This should be resolved now. Please verify.
