Fix bug #7067 - Linux asynchronous IO (aio) can cause smbd to fail to respond to a read or write.
Only works on Linux kernels 2.6.26 and above. Grants CAP_KILL capability
to allow Linux threads under different euids to send signals to each other.
Same as mater commit 899bd0005f56dcc1e95c3988d41ab3f628bb15db.
Jeremy.
