I was trying to test examples in the Gambit-c manual. I am getting the following error message

>gsi
Gambit v4.5.3

> (currentthread)
*** ERROR IN (console)@1.2 -- Unbound variable: currentthread


Do I have to 'load' something before I call 'currentthread'?

This is Gambit v4.5.3 compiled for Solaris 10.
