- Abstract unidirectional anonymous pipes into a CPipe class - Abstract a process with redirected output into a CPipedProcess class - Use these abstractions to avoid polling for output from test processes. Instead, use blocking read operations to yield the CPU while waiting for data. ROSTESTS-144 #resolve svn path=/trunk/; revision=66316
