This is fun.

Running the tcl compiler to split out the experiment copies tb_compat.tcl into
the current directory. If the fedd is running in a directory to which it
doesn't have access, strange things happen - creation fails silently.

This runs the splitter (tcl) subprocess in a directory that is guaranteed to
have proper permissions.
