[kaffe] Thread handling in Kaffe

[cal kaiwen]

Hi,

Thank you for the feedback.

Instead, me friend debug our code and found out that the exception was 
actually thrown here, not at thread creation or reuse. Is my mistake, sorry 
:)


Process p = Runtime.getRuntime().exec("ping -n 1 " + host);

p.destroy;


Eventhough the process is destroy, you can see a lot of kaffe defunct error 
message in the runnning process by doing ps -ae.

Has anyone encountered this before? Any work around for this?

Thank you,
Calvin
