Bug report

Hi Felix

I tried to build gatling, but didn't succeed, so I installed fnord. All
seemed to go well until fnord processes failed to exit and started
hogging memory. The entire build process is included below - I've only
included output where errors were indicated. fnord was serving plain
HTML content (off-line copy of cr.yp.to).

Let me know if you need anything else.

Upfront, I changed the following lines in httpd.c to the following:

#define CGI
/* #define NORMALIZE_HOST */
/* #define CHROOT */

N.B. same problem even with NORMALIZE_HOST and CHROOT defined

Details follow:

I had to place 'setuidgid' before invoking fnord, otherwise it runs as
root only!
