 In a sudden burst of inspiration I decided to check the same thing
 on PowerPC as well...
 
 # sysctl net.inet.tcp.cc.algorithm=htcp
 net.inet.tcp.cc.algorithm: newreno
 sysctl: net.inet.tcp.cc.algorithm=htcp: No such process
 
 If I replace htcp with e.g. cubic the result is quite analogous.
 So, the CC code does not seem all that healthy on PowerPC either.
 
 This PowerPC test was done using a 3 week old 9.1-STABLE...
