warn message in log summary

[Lisandro Dalcin]

After running some unittest for my new Mat Python type, I get

WARNING!!! Minimum time -1.19595e+09 over all processors for MatMult
is negative! This happens
 on some machines whose times cannot handle to rapid calls.!
 artificially changing minimum to zero.MatMult              185 1.0
-1.1959e+09 0.0 0.00e+00 0.0 0.0e+00 0.0e+00 -9.2e+02-11538114760-25
0  0-12 -11546836536-25  0  0-27     0

To minor question about this message:

* What means 'to rapid calls'?  Is it a typo? Should be 'too rapid calls' ?

* Perhaps a newline could be added after the warn mesage?
