Solaris 2.4 has a kernel bug where they fail to deliver a SIGPOLL event
when output buffer space is available. Upgrade to 2.5 or install the
kernel patch, see:
http://java.sun.com/JDK-1.0/knownbugs.html#IO
If this is in an applet, then waving the mouse should cause an X event
to be delivered to the Java runtime which should cause it to receive
a SIGPOLL and wake up and notice your write can continue. (i.e. any
other IO event will cause the write to unblock).
