Yes, I am. The doc says nothing but according to the assembly form of
this method, it do something like this:
CGContextBeginPath()
CGContextMoveToPoint()
CGContextAddLineToPoint()
CGContextStrokePath()
Most of NSBezier method are just simple wrappers upon CoreGraphics
equivalent.
An other way is to use CG directly. You can get the graphic context
using
CGContextRef ctxt = [[NSGraphicsContext currentContext] graphicPort];

Are you sure? This could be just a convenient interface for creating
a bezier object with the points passed, stroking it and releasing or
autoreleasing it. The docs say nothing about how it's implemented.
A better idea might be to create ONE bezier object at the top of the
loop, collect all the lines into it, then stroke it in one go after
the loop terminates. I do this for drawing grids with many thousands
of lines and have never hit a memory problem so far.

Yes, an a better way to fix it will be to use a static method:
[NSBezierPath strokeLineFromPoint: linebottom toPoint: linetop];
It will avoid creation of an object for each segment.
