24c3e34344 Implement a GetDataDependencyFilepath() for CMake (non-Bazel really). 
This code assumes, like Bazel's runfiles that the data dependency to access
exists in the same sub-tree as the binary:

WORKSPACE
+- sandboxed_api/sandbox2/examples/crc4
                                   +- crc4bin
                                   +- crc4sandbox

The code requires the directory structure to exist, so that in the example
above, crc4sandbox can use
  GetDataDependencyFilepath("sandboxed_api/sandbox2/examples/crc4/crc4bin")

regardless of how it was called.

Process might be killed between waitpid and PTRACE_CONT,
even though a PTRACE_EVENT_EXIT will be gererated, continuing

f29a5a81ed Print final FS mounts in sandboxee's chroot 
After all requested filesystem mounts are fully mounted under a sandboxee's virtual chroot, print a list of the outside paths and a list of the inside chroot paths that the outside paths are mapped to. This provides a valuable insight while debugging sandboxed binaries.
