While this would be better asked on mono-devel-list, there's little

Internal calls are written in C, and are in the "mono" CVS module. In
particular, in mono/metadata/icall.c is huge-ass map, icall_map, which
maps a string to a function pointer. "CurrentThread_internal" is mapped
to the C function mono_current_thread().
It's also possible to add new internal calls at runtime via

Maybe? But mono-devel-list is a better bet...
And to answer a later question, yes, post these to bugzilla, IF THEY'RE

these are already checked for in the unit tests, then I don't think they
need to be added to bugzilla, as "get the unit tests passing" is a
long-standing known issue.
