hm, what tree are you using as a base? The syslet patches are against
v2.6.20 at the moment. (the x86 PDA changes will probably interfere with
it on v2.6.21-rc1-ish kernels) Note that otherwise the syslet/threadlet
patches are for x86 only at the moment (as i mentioned in the
announcement), and the generic code itself contains some occasional
x86-ishms as well. (None of the concepts are x86-specific though -
multi-stack architectures should work just as well as RISC-ish CPUs.)

if you create a threadlet based test-webserver, could you please do a
comparable kevents implementation as well? I.e. same HTTP parser (or
non-parser, as usually the case is with prototypes ;). Best would be
something that one could trigger between threadlet and kevent mode,
using the same binary :-)
