[eigen] CTEST doesn't went through

[FMDSPAM <fmdspam@xxxxxxxxx>]

Hi Eigen Developer,

there is a regression since yesterday which let e.g. Test #37 
"integer_types_3" hang with full cpu load (=endless loop).
(Intel Core2 Duo, Vista-32, MSVC 2008 and MSVC 2010)

BTW: A Hanguptime of 1500s = approx. 1/2 hour it's pretty long time. To 
long IMHO

Cheers
Frank
