IIRC, in Frank Soltis's book on the OS/400 he talks about how not having to do 
as much context switching (due to TIMI/SLIC) allows java on that platform to 
post better perfomance than it does running on the same PowerWhatever under 
AIX/Linux. 

Also at SC23, I heard a HPE-Cray guy say that for years, they tried to get the 
low-latency jitter reduction patches into linux, but nobody was interested. 
Then, suddenly, when the guys who do music production and recording on linux 
needed that functionality...done. Priorities, I guess.
