RFR: 7152183: TEST_BUG: java/lang/ProcessBuilder/Basic.java failing intermittently [sol]

[Rob McKenna]

Hi folks,

The only way I can see this test failing in this manner[*] is if we 
destroy the process before we begin the read. That being the case I've 
jacked up the sleep (giving the reader thread a little more time to get 
cracking) and added a check to see if the threads stack has entered a 
read call.

Feedback greatly appreciated.
