The argument has been made that the increasing radiation field of an accreting star of 8-10 solar masses, will blow away further mass halting the process completely, leaving us perplexed at stars of 20, 30, 40, 50, on up solar masses...? Perhaps this is correct, an unusual core leads to infall from the accretion disk...SEE:http://arxiv.org/PS_cache/arxiv/pdf/0807/0807.3035v3.pdf

This seems to go back to some 2006 work (http://www.sciencedaily.com/releases/2006/09/060929095442.htm).

More recently, I recall seeing a model that allowed for clumpy regions in the disk to allow for regional infall, which then created a more continuous infall of material. Like having a sacrificial fullback bust through the football opponent's line to make way for the scoring tailback that got all the glory. [Did I mention I used to play fullback in high school? 3rd string, but the other guys had bad knees, so I lettered. :) ]
