 For the record, according to the logs on lyta.netbsd.org, the "p != NULL"
 failures are no longer happening, presumably fixed by Christos' commit
 of t_exhaust.c on 2021-06-09.
 
 However, the random "out of swap" failures are still happening.  The
 ATF HTML report from the most recent one is here:
 
   http://releng.netbsd.org/b5reports/evbarm-aarch64/2023/2023.02.19.21.35.07/test.html#lib_libc_regex_t_exhaust_regcomp_too_big
 
 The "out of swap" message is not in the HTML output but the console
 log, which can be found here:
