Loadraw failure after 500ish runs

Description

It appears that after a certain period of loading large numbers of raw files eventually the algorithm fails to load a file that certainly exists as it has been loaded previously.

For instance I find this conks out around iteration 504 

for i in range(0,1000):
	LoadRaw(Filename="W:/RawFiles/OFFSPEC00004990.raw",OutputWorkspace="OFFSPEC00004990",LoadLogFiles="0")
	print i

This has fairly severe implications for batch processing and Mantid has certainly not increased it's memory footprint.

(In [4214]) Missing file closure was presumably leading to us running out of file handles. Re #1172.

Tested SVN 4215

using script 

for i in range(0,10000):
	LoadRaw(Filename="C:/Mantid/Test/Data/OFFSPEC00004622.raw",OutputWorkspace="OFFSPEC00004622",LoadLogFiles="0")
	print i

Tested to 10000 iterations

Very slow rise in memory from 140M to 255MB over the test
