 Basically I don't understand what you mean by "stuck in WAIT state".
 What's so bad about the WAIT state in your opinion?  Why being in that state
 implies being "stuck"?
 As far as I understand it's a normal state for the interrupt threads when they
 are not servicing any interrupts.  Do you have a different understanding?
