System Information
Operating system: Linux x86_64
Graphics card: GeForce GTX 1080 Ti

Blender Version
Broken: 2.90.1 stable
Worked: N/A

Short description of error
The Remesh Modifier's Voxel Size parameter can easily cause Blender to freeze/crash. This is a design flaw of the Voxel Size parameter itself. As the value approaches zero, the resulting complexity approaches infinity.

Exact steps for others to reproduce the error
Add a Remesh modifier to a mesh object (Mode: Voxel)
Drag the Voxel Size parameter toward zero.
Blender will freeze, filling up RAM, possibly until the OS is forced to kill it.

PROPOSAL
"Voxel Size" should instead be expressed as its reciprocal, i.e. "Voxels per Blender Unit".
