ignore_data=True no longer works properly

[rct01]

In version 0.27 using ignore_data=True in lasio.read would result in the file headers being read incredibly quickly. Some timings:

Since version 0.28 ignore_data=True has far less effect. Opening the same files in 0.28+

My application is designed to scan hundreds of files and determine their contents. This issue means I cant upgrade past 0.27. Any help would be much appreciated.
