[Wine] Strange slowdown calling Wine from PHP

[Bruce Fletcher]

I'm getting some odd behaviour from Wine when I call it from PHP, and
I was wondering if someone who has the command line version of PHP
installed would be willing to give the following test a try to see if
it is something local to me or not.

When I call Wine from a PHP script, it runs perfectly quickly.  When I
call that PHP script from another one, the whole thing slows down
dramatically.  Here's a geeky summary:

temp$ which php
/usr/local/bin/php
temp$ ls
bar.php  foo.php
temp$ cat foo.php
#!/usr/local/bin/php
<?php

`./bar.php`;

?>
temp$ cat bar.php
#!/usr/local/bin/php
<?php

`wine --version`;

?>
temp$ time wine --version
Wine 20041019

real    0m0.016s
user    0m0.002s
sys     0m0.006s
temp$ time ./bar.php
Wine 20041019

real    0m0.023s
user    0m0.008s
sys     0m0.006s
temp$ time ./foo.php
Wine 20041019

real    0m3.034s
user    0m0.013s
sys     0m0.008s


Note the 3 second real time penalty for calling Wine from the second
level PHP script.

I don't see this with other utilities called from PHP, and I don't see
this problem with Wine called from shell scripts.  If someone could
run foo.php and bar.php and post what they see, I'd appreciate it.

Thanks,

PS, I'm running PHP 4.3.9 on 64-bit Fedora Core 2, for reference.
