[cap-talk] Confessions of a C programmer

[Ben Kloosterman]

I have used Java on Arm  it is sluggish not so much the JVM load but the
JIT.

The problem with all these ( and C# etc) is the libs can you skip / hack the
libs ? I suppose c libs have a similar issue as malloc will eventually do a
syscall. 

Regards ,

Ben
