Subject: Make downloader delay a class-variable
X-Git-Url: https://git.rkrishnan.org/components/com_hotproperty/something?a=commitdiff_plain;h=c2464bb210c7b641855f1cf7b684838a6619b5d8;p=tahoe-lafs%2Ftahoe-lafs.git

Make downloader delay a class-variable

This gives the integration-style CLI-based tests a chance
to set the delay to 0 before the first 3-second delayed
call is queued to _lazy_tail in the Downloader
