An apparatus includes a buffer, a sequencing circuit, and an execution unit. The buffer may be configured to store a plurality of instructions. Each of the plurality of instructions may be in a first thread. In response to determining that the first instruction depends on the value of a condition variable and to determining that a count value is below a predetermined threshold, the sequencing circuit may be configured to add a wait instruction before the first instruction. The execution unit may be configured to delay execution of the first instruction for an amount of time after executing the wait instruction. The sequencing circuit may be further configured to maintain the plurality of instructions in the first buffer after executing the wait instruction, and to decrement the count value in response to determining that the value of the condition variable is updated within the amount of time.
