it is really unclear what you are asking. What is the functional form of a "basically partial and scewed limacon"?

Glad to know there is a workaround, but this ought to be reported to wolfram support.

comment Mathematica integration failure - new or old?
9.0.1 gets a correct analytic result for the definite integral If I add Assumptions->{a>0,b>0} (Takes a very long time though )

comment How can I read compressed .Z file automatically by Mathematica?
try: Import["!uncompress -c file","format"]. I think the -c sends to stdout. (I don't seem to have compress on my system )

comment Mathematica's equivalent to the Python's Zip command in List-comprehension?
MapThread[Function[{x,y,x},x+y+z],{xlist,ylist,zlist}] is pretty darn close to [x+y+z fir x,y,z in zip(xlist,ylist,zlist)]

comment Export[] performance
I believe the bottleneck is not i/o but in the string conversion . Note ExportString and even Map[ToString,exp,{2}] give similar timing.
