It's a long-known fact that the AIX /bin/sh is painfully slow due to
this.  The GCC install manual has recommended setting CONFIG_SHELL to
bash for years.

We could consider special-casing AIX, or preferring bash in any case.
Neither of which I'd like to do before 2.60, nor any other changes to
the shell selection.  Adding a recommendation for setting CONFIG_SHELL
to bash would be rather safe, though.

BTW, does the flooding lead to /tmp being full, /bin/sh running out of
file descriptors, running out of file names, or did you just kill it at
one point while it was still running?
