Hello,

I'm sorry to send Japanese mail to this mailing list.

The mail I sent is about sigwait support for Gauche.
Sigwait provides an easy and reliable way to handle Unix
signal in a multi-threaded environment.  With my patch,
you can write a multi-threaded application in the following
way:

 (1) At first, you have to ensure that all threads block
    signals that you want to handle.
 (2) Signal-handling thread calls sys-sigwait() and wait
    for arrival of signal.  When signal arrives, sys-sigwait()
    returns the signal number, instead of calling signal
    handler function.
 (3) You can dispatch with the signal number, and process
    the signal.

I hope this feature helps you when you write a reliable
application.

thanks,
