I have tested it on GNU/Linux x86_64 (Ubuntu 9.04) and it is working
fine, but it still segfaults on Linux 32bit with the message "Collecting
from unknown thread.". The main thread calls cl_boot() when application
is started, ecl_import_current_thread() gets called in the second thread
before other calls to ECL:
