Re: [Tclhttpd-users] Memory Usage & cgi's

[Brent W. <bre...@in...>]

Whatever is in your CGI script will have no affect - that's
a different process.  You might try looking at
/status/size
which returns the number of bytes used for data and code at the
Tcl script level.  It won't highlight any leaks in the C core,
but there shouldn't be many of those.  Hmm - there is some possibility
of a leak in exec on Windows - but I thought that was only in certain
cases - I'll have to check on that.
