It might, but that is adding no significant delay, and the
results are unpredictable.
jinx$ echo value | { read -t 0 var; } ; echo $?
0
jinx$ echo value | { read -t 0 var; } ; echo $?
0
jinx$ echo value | { read -t 0 var; } ; echo $?
1
jinx$ echo value | { read -t 0 var; } ; echo $?
1
jinx$ echo value | { read -t 0 var; } ; echo $?
0
jinx$ echo value | { read -t 0 var; } ; echo $?
1
jinx$ echo value | { read -t 0 var; } ; echo $?
1
jinx$ echo value | { read -t 0 var; } ; echo $?

jinx$ echo value | { read -t 0 var; } ; echo $?

jinx$ echo value | { read -t 0 var; } ; echo $?

jinx$ echo value | { read -t 0 var; } ; echo $?

It is all just a race condition - there's nothing specifying which
side of the pipe starts running first.
