In CL 656755, the readRandom function was modified to read an integer from /dev/random. However, on Plan 9, /dev/random can only return a few hundred bits a second. The issue is that readRandom is called by randinit, which is called at the creation of Go processes. Consequently, it lead the Go programs to be very slow on Plan 9. This change reverts the change done in CL 656755 to make the readRandom function always returning 0 on Plan 9.
