Unfortunately, that's what Posix says.  If you look at the table at
http://pubs.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html#tag_15_04_03
you'll see a list of Posix functions that it's safe to call from a
signal handler, and malloc() and free(), or anything traditionally
implemented using either one, is not on that list.  The reason is that
most C libraries don't have reentrant allocators.
