I don't know what the problem is, but there is an interesting variation of
this problem that Mathematica has no problem with. Simply interchange
the order of x and y in the variable list and instead of getting
stuck in a loop as in the first case, Mma appears to give to proper
solutions to the problem. That is why doesn't Mathematica have the
same problem with
Solve[{a x^2 + b y^2 == 1, a x + b y == 1}, {y,x}] ?
