Well, except that maintaining it is beyond most mortals. 
And one of
my clients is having some dependency problems with parallel
builds of
Boost using distcc.  Not clear yet whether that's a Jamfile
error or a
bug in the core build system.

One would hope so, anyway.

I never tried to maintain any other build engine, so can't
really comment if 
jam code is some bad compared to other. Anyway, I've no
problem with using 
better code if there is one.

I guess it's a bit early to blame this on jam, then.
