Linking with guile with qthreads is optional , there's a configure commandline
switch to enable/disable it.
Maybe it will be reconfigured as a module later, or become obsolete when 
kernel threads get supported. Threads can also be emulated by scheme coroutines
passing control mutually via call-with-current-continuation or maybe  guile's
exceptions, if one doesn't want threads for multiprocessing.
