Yuk.
Tcl seems to be the only language that is thread safe and can be embedded in the way it is in AOLserver. And like others have said: AOLserver actually uses a lot of the Tcl API. Most Tcl commands have a C equivalent that can be used outside an interpreter. With the few C modules I have made good use of this, using the String functions and not relying on things like glibc, for instance. (even glibc itself has many threading issues; I tried the str functions and in a high-load concurrent environment, they blew up and segfaulted.)
