I have investigated more - the failing test is
bamtools filter -script tests/filter_script -in sam_spec_example.bam
-out out.bam

all other tests pass.

... and that forever
I have changed the filter_script to add more lines of data, and trace
shows like at the end of file it doesn't get EOF and try to read more -
don't understand why !
