Mike Stroyan f0a60e47b1 Don't use fstat for readable pipe chars in dtexec. ...

The dtexec code assumes that fstat reports pipe's readable chars.
Linux always reports 0 for st_size of a pipe.
Instead read one character when select reports readable.
Note EOF when select says readable but read returns 0.
