Redirect a filehandle from a currently running process.

This command uses the debugger to attach to a running process, and reassign a filehandle to a file.

The two commands executed in gdb are

p close(1) which closes STDOUT

and

p creat("/tmp/filename",0600)

which creates a file and opens it for output. Since file handles are assigned

sequentially, this command opens the file in place of STDOUT and once the process continues, new output to STDOUT will instead be written to our capture file.
