Yes, that Perl section forms your real startup script and now that the
mod_perl config engine is fully reentrant your $PerlRequire was recursing
into perl_section before the original %ApacheReadConfig was cleaned.

I think the better is to include it in the macro definition in mod_perl.h:
#ifdef PERL_SECTIONS
# ifndef PERL_SECTIONS_SELF_BOOT
# ifdef WIN32
-# define PERL_SECTIONS_SELF_BOOT getenv("PERL_SECTIONS_SELF_BOOT")
+# define PERL_SECTIONS_SELF_BOOT \
+ (getenv("PERL_SECTIONS_SELF_BOOT")&&!perl_sections_self_boot)
# else
-# define PERL_SECTIONS_SELF_BOOT 1
+# define PERL_SECTIONS_SELF_BOOT !perl_sections_self_boot
# endif
# endif
#endif
And document the fact that only the true directives PerlModule and
PerlRequire can trigger the scan of the %ApacheReadConfig namespace but
not $PerlModule nor $PerlRequire.
Anyway %ApacheReadConfig:: isn't documented in the main docs, and that is
the main reason that many people are using long <Perl>...</Perl> sections
that can be sustituted by a simple and cleaner "PerlRequire foobar".
