I have been running WSPR for about 18 hours on Mac OSX 10.9 until it crashed
with:
Error in soundin, Error -9981, Error message: Input overflowed.
Before it crashed, top reported:

Conclusion: if seems WSPR is leaking but not as extensively as WSJT. I have
a gzipped file of vmmap but at 27k it might be too big to be accepted by the
list server.
Still investigating...
