Since we'll have multiple cpu threads, at least for kvm, we need

For the I/O thread, this will be NULL.
I am using pthread functions for that, for portability, but we
could as well
use __thread keyword.
Where is __thread not supported?
Apple, Sun.
Well, pthread_getspecific is around 130 bytes of code, whereas
__thread is just on instruction. Maybe we should support both.
Maybe. Mono does so, they have some autoconf-based check plus a
configure switch --with-tls={pthread|__thread} to override.
