Monitor의 condvar가 하나일 필요가 없나?

answer from bing chat#

Yes, it is possible to have more than one conditional variable in a monitor. A conditional variable is a queue of threads that are waiting for some condition to become true. A monitor can use one or more conditional variables to coordinate the access and signaling of shared variables and operations¹.

For example, a bounded buffer monitor can use two conditional variables: one for items available and one for slots available. The producer threads can wait on the slots available condition variable before adding an item to the buffer, and signal the items available condition variable after adding an item. The consumer threads can wait on the items available condition variable before removing an item from the buffer, and signal the slots available condition variable after removing an item¹.
