Re: [gentoo-dev] Making NPTL the default

[Daniel Goller]

Great work, the snapshot works great for quite some time now, being on 
nptl by default but LD_ASSUME_KERNEL=2.4.x should i want to test things, 
if noone sees a benefit in it, at least it makes everyone's life testing 
bugs easier this way.
