RFR: JDK-8158629: bash >(...) construct still causes race conditions

[Erik Joelsson]

Hello,

I think I have finally found a solution for the race condition in the 
build caused by the >(tee logfile) construct. See bug comments for 
details. It's very hard to prove if the solution is valid, but at least 
my isolated test case was fixed using the same strategy. Only time will 
tell if this finally rids us of this annoying problem.
