Suggest you use a proper reset circuit such as Microchip's MCP809/810
(or the TO-92 versions). Similar parts are available from Seiko, Motorola,
and many others. You can make your circuit less sensitive by paralleling
R1/R2 with similar ratio capacitors, but it's still going to be a crummy
temperature-sensitive circuit without timer or hysteresis. Unless you
are building very high volume goods, it just ain't worth it.
