Related to #44109, #43884, #43809. In the Linux dispatcher, we create one background thread per CPU, but when a single core is available, having a single background thread significantly hinders the perceived performance of Zed. This is particularly helpful when SSH remoting to low-resource servers. We may want to bump this to more than two threads actually, but I wanted to be conservative, and this seems to make a big difference already. Release Notes: - N/A

when a single core is available, having a single background thread
significantly hinders the perceived performance of Zed. This is
particularly helpful when SSH remoting to low-resource servers.
We may want to bump this to more than two threads actually, but I wanted
to be conservative, and this seems to make a big difference already.
