Well I don't work for Software Components Group so I feel I can rebut.
pSOS is not intended to be Unix compatible and if Roger wasted time
trying to make it so then he is the one who made the mistake.  pSOS
absolutely is not 'crippled' and is an excellent real time kernel
(from experience) and I have seen at least one independent, indepth
review of real time kernels that ranked it as the best.
