If you don't use SIGIO, I can't see how malloc/free could be interrupted.
What other signals are used?

Also, do a grep for "SYNC_INPUT", which is a compilation option I use to
make the Xwindow code move most of the processing to outside of the signal
handler (when compiled with SYNC_INPUT, the "interrupted malloc" should
simply never be a problem and the BLOCK_INPUTS there are unnecessary).
