Azle calling `setTimer` causes infinite loop of timers
Summary
Azle calling setTimer causes infinite loop of timers
Original description
The description as published by the source.
Azle is a WebAssembly runtime for TypeScript and JavaScript on ICP. Calling setTimer in Azle versions 0.27.0, 0.28.0, and 0.29.0 causes an immediate infinite loop of timers to be executed on the canister, each timer attempting to clean up the global state of the previous timer. The infinite loop will occur with any valid invocation of setTimer. The problem has been fixed as of Azle version 0.30.0. As a workaround, if a canister is caught in this infinite loop after calling setTimer, the canister can be upgraded and the timers will all be cleared, thus ending the loop.
