[BUG] btop coredumps, !dequeue->empty() failed

[ItsMeSamey]

Describe the bug

Btop core dumps (only sometimes)

To Reproduce

Not exactly sure but the issue seems to be related with "cpu's being off-lined"
I have written a small program to turn off/on cpu cores using echo 0 > /sys/devices/system/cpu/cpuX/online, that is when the issue started happening.
the issue is quite rare (because off-lining is rare, and rarely happens at the same time of launching btop)
