Hello everyone,

I have found the -T option for parallel building to be unreliable. Has anyone 
else? It doesn't seem to have had wide exposure yet and several commonly used 
packages are not yet marked as thread safe, but I was hoping for better results 
than I am seeing.

The problem I am getting is that when it fails a random module fails to find 
some external jar that I know is there. For my project the most common 
occurrence is failure to find javax.servlet but it really is there and a serial 
build finds it. I am at a loss to understand how this can be happening.

I am very keen indeed to get the -T option working because I have recently 
added use of the maven-jarsigner to the mix and the network I am using is slow 
and unreliable. A serial build with jar signing doubles the build time. When 
the parallel build works (which it does occasionally) the build time is reduced 
by an order of magnitude.
