Ah. That delay actually occurs when the actual file picker (for lack of
a better term) displays the /usr/bin directory.
The amazing thing is what it's doing. This includes:
open /usr/bin
getdents
for each file
stat it (to get modification time?)
That's reasonable, and most programs would stop here with about .2
seconds used. Although a non-generic "pick a program to use" chooser
shouldn't need to even care about getting modification times, which
would bring it down to more like 0.001 seconds used.
for each file
open file
use fstat on it (to get modification time? again?)
read 4k of file contents, apparently to determine the file type
to use in displaying various (identically meaningless) icons
The second loop is the killer when it needs to read 3000 files. Tens of
thousands of system calls, and the disk seeking all around to read some
12 mb of data. Pretty absurd indeed.
