Well if I can figure out how to repeat it on demand, I'll ktrace it
more.

What's the meaning of the "No such file or directory" error that is
being returned?  The manpage for sigreturn() doesn't list ENOENT as
a valid error return code.  Looking at linux_sys_sigreturn I don't
see where it would return ENOENT, just EFAULT, or EINVAL.
Or is this return value being set by the netscape signal handler?

Thanks.
